It takes serial data on one input line and, after eight clock pulses, presents the full 8-bit word on parallel outputs. The push-pull outputs can source or sink current directly, so you can drive LEDs or small relays without a buffer. The 74HC logic family means it runs from a 2V to 6V supply, making it compatible with both 3.3V and 5V systems. ## Where you would use it Typical applications include expanding the output pins of a microcontroller — think adding eight more outputs for controlling LEDs, seven-segment displays, or latching relays. The 14-SOIC package is a common footprint that fits on a standard 0.1-inch-pitch prototyping board with adapter. ## Lifecycle and sourcing reality The SN74HC164NS is listed as Active and ROHS3 compliant. For a BOM line, this part carries no last-time-buy risk.

The SN74HC164NS updates its outputs directly on each clock pulse, so it is simpler but lacks the output-latch feature. If you need to update outputs synchronously without glitches, the SN74HC595 is the better fit."},{"question":"Is the SN74HC164NS a serial to parallel shift register?","answer":"Yes, the SN74HC164NS is an 8-bit serial-to-parallel shift register.
