Frequently Asked Questions
What is the CD74HC165M used for?
The CD74HC165M is an 8-bit parallel-in/serial-out shift register used to expand microcontroller inputs via a serial interface. By daisy-chaining multiple devices, you can read dozens of parallel inputs using only 3 MCU pins (CLK, LOAD, DATA), making it ideal for keyboard scanning, DIP switch reading, and sensor polling in embedded systems.
What is the supply voltage range for the CD74HC165M?
The CD74HC165M operates from 2V to 6V, compatible with both 3.3V and 5V logic systems. At 5V, the typical propagation delay is 13ns. The wide supply range ensures compatibility with modern low-voltage MCUs as well as legacy 5V designs.
What package is the CD74HC165M available in?
The CD74HC165M comes in the SOIC-16 surface-mount package with 16 pins on a 1.27mm pitch. Texas Instruments also offers the CD74HC165E in PDIP-16 for through-hole and the CD74HC165PW in TSSOP-16 for higher-density boards.
What are compatible replacements for the CD74HC165M?
Pin-compatible alternatives include SN74HC165DR from TI, MC74HC165ADR2G from onsemi, and 74HC165D from Nexperia. All share the 8-bit PISO function, SOIC-16 package, and 2V to 6V supply range.
Is the CD74HC165M RoHS compliant?
Yes, the CD74HC165M is RoHS compliant and lead-free. Texas Instruments ships it with a Pb-free finish meeting IEC 62321 and EU RoHS 2 directives. MSL rating is level 1 per JEDEC J-STD-020.
