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 74HC/HCT194 and shifted from left to right (Q0 → Q1 → Q2, etc.) or, right to left (Q3 → Q2 → Q1, etc.) or parallel……
