DESCRIPTION

HCF40104B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP packages.

HCF40104B is a universal shift register featuring

parallel inputs, parallel outputs, SHIFT RIGHT and

SHIFT LEFT serial inputs, and a high-impedance

third output state allowing the device to be used in

bus-organized systems. In the parallel-load mode

(SO and S1 are high), data is loaded into the

associated flip-flop and appears at the output after

the positive transition of the CLOCK input. During

loading, serial data flow is inhibited. Shift-right and

shift-left are synchronously accomplished on the

positive clock edge with serial data entered at the

SHIFT RIGHT and SHIFT LEFT serial inputs,

respectively. Clearing the register is accomplished

by setting both mode controls low and clocking the

register. When the output enable input is low, all

outputs assume the high impedance state.
