M74HC164B1R

Shift Registers Overview

The M74HC164B1R is an 8-bit serial-in parallel-out shift register from the HC logic family, manufactured using silicon gate C2MOS technology. It operates within a supply voltage range of 2V to 6V and features asynchronous master reset functionality. The device includes two data inputs (A and B) that function as active-high enables for serial entry. Data shifts on low-to-high clock transitions, with outputs QA through QH reflecting the NAND logic of the inputs at each stage.
