GENERAL DESCRIPTION
The 74HC/HCT597 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 74HC/HCT597 consist each of an 8-bit storage
register feeding a parallel-in, serial-out 8-bit shift register.
Both the storage register and the shift register have
positive edge-triggered clocks. The shift register also has
direct load (from storage) and clear inputs.
