  • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT194 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. The functional characteristics of the 74HC/HCT194 4-bit bidirectional universal shift registers are indicated in the logic diagram and function table. The registers are fully synchronous. The “194” design has special features which increase the range of application. The synchronous operation of the device is determined by the mode select inputs (S0, S1). As shown in the mode select table, data can be entered QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns
