FEATURES
GENERAL DESCRIPTION
The 74HC/HCT40104 are high-speed Si-gate CMOS
devices and are pin compatible with the “40104” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT40104 are universal shift registers
featuring parallel inputs, parallel outputs, shift-right and
shift-left serial inputs and 3-state outputs allowing the
devices to be used in bus-organized systems.

loaded into the associated flip-flop and appears at the
output after the positive transition of the clock input (CP).
During loading, serial data flow is inhibited. Shift-right and
shift-left are accomplished synchronously on the positive
clock edge with serial data entered at the shift-right (D

Clearing the register is accomplished by setting both mode
