74HC/HCT194 4-bit bidirectional universal shift register
Product specification File under Integrated Circuits, IC06 December 1990
Philips Semiconductors
Product specification
4-bit bidirectional universal shift register
FEATURES Shift-left and shift-right capability Synchronous parallel and serial data transfer Easily expanded for both serial and parallel operation Asynchronous master reset Hold (“do nothing”) mode Output capability: standard 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
