MM54HC597/MM74HC597
8-Bit Shift Registers with Input Latches
General Description
This high speed shift register utilizes advanced silicon-gate
CMOS technology. It has the high noise immunity and low
power consumption of standard CMOS integrated circuits,
as well as the ability to drive 10 LS-TTL loads.
The 'HC597 comes in a 16-pin package and consists of an
8-bit storage latch feeding a parallel-in, serial-out 8-bit shift
register. Both the storage register and shift register have
positive-edge triggered clocks. The shift register also has
direct load (from storage) and clear inputs.
The 54HC/74HC logic family is speed, function, and pin-out
compatible with the standard 54LS/74LS logic family. All
inputs are protected from damage due to static discharge by
internal diode clamps to VCC and ground.
