DM74LS181 4-Bit Arithmetic Logic Unit General Description The DM74LS181 is a 4-bit Arithmetic Logic Unit (ALU) which can perform all the possible 16 logic operations on two variables and a variety of arithmetic operations.

DM74LS181 Functional Description The DM74LS181 is a 4-bit high speed parallel Arithmetic Logic Unit (ALU). Controlled by the four Function Select inputs (S0 S3) and the Mode Control input (M), it can perform all the 16 possible logic operations or 16 different arithmetic operations on active HIGH or active LOW operands. The Function Table lists these operations When the Mode Control input (M) is HIGH, all internal carries are inhibited and the device performs logic operations on the individual bits as listed. When the Mode Control input is LOW, the carries are enabled and the device performs arithmetic operations on the two 4-bit words. The device incorporates full internal carry lookahead and provides for either ripple carry between devices using the C n+4 output, or for carry lookahead between packages using the signals P (Carry Propagate) and G (Carry Generate). In the ADD mode, P indicates that F is 15 or more, while G indicates that F is 16 or more. In the SUBTRACT mode, P indicates that F is zero or less, while G indicates that F is less than zero. P and G are not affected by carry in. When speed requirements are not stringent, it can be used in a simple ripple carry mode by connecting the Carry output (C n+4 ) signal to the Carry input (C n ) of the next unit. For high speed operation the device is used in conjunction with the 9342 or 93S42 carry lookahead circuit. One carry lookahead package is required for each group of four DM74LS181 devices. Carry lookahead can be provided at various levels and offers high speed capability over extremely long word lengths. The A = B output from the device goes HIGH when all four F outputs are HIGH and can be used to indicate logic equivalence over four bits when the unit is in the subtract mode. The A = B output is open-collector and can be wired- AND with other A = B outputs to give a comparison for more than four bits. The A = B signal can also be used with the C n+4 signal to indicate A > B and A < B. The Function Table lists the arithmetic operations that are performed without a carry in. An incoming carry adds a one to each operation. Thus, select code LHHL generates A minus B minus 1 (2s complement notation) without a carry in and generates A minus B when a carry is applied. Because subtraction is actually performed by complementary addition (1s complement), a carry out means borrow; thus a carry is generated when there is no underflow and no carry is generated when there is underflow. As indicated, this device can be used with either active LOW inputs producing active LOW outputs or with active HIGH inputs producing active HIGH outputs. For either case the table lists the operations that are performed to the operands labeled inside the logic symbol.

SN54/74LS195A LOGIC DIAGRAM FUNCTIONAL DESCRIPTION The Logic Diagram and Truth Table indicate the functional characteristics of the LS195A 4-Bit Shift Register. The device is useful in a wide variety of shifting, counting and storage applications. It performs serial, parallel, serial to parallel, or parallel to serial data transfers at very high speeds. The LS195A has two primary modes of operation, shift right (Q0 Q1) and parallel load which are controlled by the state of the Parallel Enable (PE) input. When the PE input is HIGH, serial data enters the first flip-flop Q0 via the J and K inputs and is shifted one bit in the direction Q0 Q1 Q2 Q3 following each LOW to HIGH clock transition. The JK inputs provide the flexibility of the JK type input for special applications, and the simple D type input for general applications by tying the two pins together. When the PE input is LOW, the LS195A appears as four common clocked D flip-flops. The data on the parallel inputs P0, P1, P2, P3 is transferred to the respective Q0, Q1, Q2, Q3 outputs following the LOW to HIGH clock transition. Shift left operations (Q3 Q2) can be achieved by tying the Qn Outputs to the Pn 1 inputs and holding the PE input LOW. All serial and parallel data transfers are synchronous, occurring after each LOW to HIGH clock transition. Since the LS195A utilizes edge-triggering, there is no restriction on the activity of the J, K, Pn and PE inputs for logic operation except for the set-up and release time requirements. A LOW on the asynchronous Master Reset (MR) input sets all Q outputs LOW, independent of any other input condition.

SN54/74LS195A DEFINITIONS OF TERMS SETUP TIME(ts) is defined as the minimum time required for the correct logic level to be present at the logic input prior to the clock transition from LOW to HIGH in order to be recognized and transferred to the outputs. HOLD TIME (th) is defined as the minimum time following the clock transition from LOW to HIGH that the logic level must be maintained at the input in order to ensure continued recognition. A negative HOLD TIME indicates that the correct logic level may be released prior to the clock transition from LOW to HIGH and still be recognized. RECOVERY TIME (trec) is defined as the minimum time required between the end of the reset pulse and the clock transition from LOW to HIGH in order to recognize and transfer HIGH Data to the Q outputs. AC WAVEFORMS The shaded areas indicate when the input is permitted to change for predictable output performance. Figure 1. Clock to Output Delays and Clock Pulse Width Figure 3.
