Overview
The 74HCT164D,653 is an 8-bit serial-in, parallel-out shift register manufactured by Nexperia. This component is part of the 74HCT series, known for its high-speed Si-gate CMOS technology. It is designed to operate within a supply voltage range of 4.5 V to 5.5 V, making it compatible with TTL (Transistor-Transistor Logic) level inputs.
The device features two serial data inputs (DSA and DSB) and eight parallel data outputs (Q0 to Q7). Data is shifted on the LOW-to-HIGH transitions of the clock (CP) input, and a LOW on the master reset input (MR) clears the register and forces all outputs LOW.
