Description
The Harris CD74HC597 and CD74HCT597 are high-speed
silicon gate CMOS devices that are pin-compatible with the
LSTTL 597 devices. Each device consists of an 8-flip-flop
input register and an 8-bit parallel-in/serial-in, serial-out shift
register. Each register is controlled by its own clock. A “low” on
the parallel load input (PL) shifts parallel stored data asyn-
chronously into the shift register. A “low” master input (MR)
clears the shift register. Serial input data can also be synchro-
nously shifted through the shift register when PL is high.
