8-bit shift register with input latches
FEATURES 8-bit parallel input latches Shift register has direct overriding load and clear Output capability: standard ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT7597 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.
74HC/HCT7597
The 74HC/HCT7597 both consist of an 8-bit storage latch feeding a parallel-in, serial-out 8-bit shift register. When LE is LOW, data at the Dn inputs enter the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D-input changes. When LE is HIGH the latches store the information that was present at the D-inputs, a set-up time preceding the LOW-to-HIGH transition of LE. The shift register has a positive edge-triggered clock, direct load (from storage) and clear inputs.
