Product Overview
ON Semiconductor MC74HC165AN 8-bit parallel-in serial-out (PISO) shift register in a PDIP-16 package. Commonly used for input expansion - reading multiple switches or digital signals with only a few microcontroller or PLC pins.
Key Features
- Logic function: 8-bit parallel-in / serial-out (PISO) shift register
- Logic family: 74HC high-speed CMOS
- Supply voltage range: 2.0 V to 6.0 V
- Package: PDIP-16 (through-hole, 16-pin DIP)
- Inputs: Asynchronous parallel load, gated clock inputs
- Output drive: Can drive up to 10 LSTTL loads
- Absolute maximum supply voltage: 7.0 V (do not exceed)
Applications
- GPIO / input expansion for microcontrollers and PLCs

- Daisy-chained shift-in input stages for displays and control boards
Frequently Asked Questions
Is this a shift-in part (parallel-in serial-out) or a shift-out part like the 74HC595?
Shift-in. The MC74HC165AN is an 8-bit parallel-in serial-out shift register.
What supply voltage does it require?
2.0 V to 6.0 V DC. Do not exceed 7.0 V absolute maximum.
Is this the through-hole DIP version?
Yes. MC74HC165AN is the PDIP-16 package.
Is this lead-free / Pb-free?
Not confirmed. Lead-free status typically depends on the specific suffix/marking (often a "G"), which is not provided.
