8-bit static shift register

HEF4014B

MSI

DESCRIPTION

The HEF4014B is a fully synchronous edge-triggered 8-bit

static shift register with eight synchronous parallel inputs

synchronous parallel enable input (PE), a LOW to HIGH

edge-triggered clock input (CP) and buffered parallel

Operation is synchronous and the device is edge-triggered

on the LOW to HIGH transition of CP. Each register stage

is of a D-type master-slave flip-flop. When PE is HIGH,

to HIGH transition of CP. When PE is LOW, data is shifted

is shifted one position to the right on the LOW to HIGH

transition of CP. Schmitt-trigger action in the clock input

makes the circuit highly tolerant to slower clock rise and

fall times
