CD74HC597E Datasheet PDF - TI

The CD74HC597E is a 8-bit CMOS Shift Register with input storage. It is 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 asynchronously into the shift register. A "low" master input (MR\\) clears the shift register. serial input data can also be synchronously shifted through the shift register when PL\ is high.
