DESCRIPTION
The HEF4014B is a fully synchronous edge-triggered 8-bit
static shift register with eight synchronous parallel inputs
(P
synchronous parallel enable input (PE), a LOW to HIGH
edge-triggered clock input (CP) and buffered parallel
outputs from the last three stages (O

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,
data is loaded into the register from P
to HIGH transition of CP. When PE is LOW, data is shifted
to the first position from D
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
