Philips 74F164 8-bit Serial-in Parallel-out Shift Register Datasheet

About this manual

The Philips 74F164 is an integrated circuit designed as an 8-bit edge-triggered shift register. It features gated serial data inputs (Dsa, Dsb) that allow data to be entered through one of two inputs, which can also serve as active-high enables for the other input. The device shifts data one place to the right on each Low-to-High transition of the clock (CP) input.

Frequently asked questions

How is data entered into the register?

Data is entered through one of two inputs (Dsa, Dsb), where either input can act as an active High enable for data entry through the other.

What happens when a Low level is applied to the Master Reset (MR) input?

A Low level on the MR input overrides all other inputs and clears the register asynchronously, forcing all outputs Low.

Can multiple 74F164 devices be connected together?

Yes, the device can be cascaded to form synchronous shift registers of longer length.
