2 7C/CT16 FEATURES Gated serial data inputs Asynchronous master reset Output capability: standard I CC category: MSI GENERAL DESCRIPTION The 7C/CT16 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. Data is entered serially through one of two inputs (D sa or D sb ); either input can be used as an active IG enable for data entry through the other input. Both inputs must be connected together or an unused input must be tied IG. Data shifts one place to the right on each LOW-to-IG transition of the clock (CP) input and enters into Q 0, which is the logical AND of the two data inputs (D sa,d sb ) that existed one set-up time prior to the rising clock edge. A LOW level on the master reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all outputs LOW. The 7C/CT16 are 8-bit edge-triggered shift registers with serial data entry and an output from each of the eight stages.
