Rev. 6 — 15 September 2021
Product data sheet
1. General description
The 74LV164 is an 8-bit serial-in/parallel-out shift register. The device features two serial data inputs (DSA and DSB), eight parallel outputs (Q0 to Q7). Data is entered serially through DSA or DSB and either input can be used as an active HIGH enable for data entry through the other input. Data is shifted on the LOW-to-HIGH transition of the clock input (CP). A LOW on the master reset input (MR) clears the register and forces all outputs LOW, independently of other inputs.
Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess VCC.
2. Features and benefits
• Wide supply voltage range from 1.
