1 U74C563 UNISONIC TECNOOGIES CO., TD OCTA TRANSPARENT D-TYPE ATCES WIT 3-STATE OUTPUTS DESCRIPTION The U74C563 is a octal traparent D-TYPE latches with 3-state outputs. When the latch-enable (E) is high, the Q outputs follow the complements of the D inputs. When E is low, the Q outputs are latched at the inverses of the levels set up at the D inputs. When the output-enable ( OE ) input is high, the Q outputs are in a high-impedance state, and the outputs neither load nor drive the bus lines. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pull-up components. While the outputs are in the high-impedance state, old data can be retained or new data can be entered, i.e. OE does not affect the internal operatio of the latches. When OE is low, the Q outputs are in a normal logic state (high or low levels). The U74C563 is designed for 1.65 to 3.6 operation. Inputs can be driven from either 3.3 or 5 devices, so the U74C563 can be used in a mixed 3.3/5 system environment. To eure the high-impedance state during power up or power down, OE should be tied to CC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. FEATURES * Wide supply voltage range from 1.65 to 3.6 * Max t PD of 6.8 from D to Q at 3.3 * Max t PD of 7.6 from E to Q at 3.3 * Up to 5.5 inputs accept voltages * ow power coumption, I CC = 10μA (Max.) at 3.6 * ±24mA output driver at 3 * I OFF supports partial-power-down mode operation ORDERING INFORMATION Ordering Number ead Free alogen Free Package Packing U74C563-P20-R U74C563G-P20-R TSSOP-20 Tape Reel U74C563-P20-T U74C563G-P20-T TSSOP-20 Tube 1 of 6 Copyright 2011 Unisonic Technologies Co., td
