Frequently Asked Questions
What are the key specifications of the SN74HC165DR?
The SN74HC165DR is an 8-bit parallel-load shift register operating from 2 V to 6 V. It features a maximum shift-clock frequency of 85 MHz at 4.5 V, 24 mA output drive strength, complementary Q/Q̄ outputs, and a 16-pin SOIC package. Operating temperature range is -40°C to +85°C.
What is the SN74HC165DR typically used for?
It is commonly used to expand the digital inputs of microcontrollers via SPI: connecting 8 push-buttons, DIP switches, or sensors and reading their states with just three MCU pins (CLK, SH/LD, DATA). It is also used in industrial control panels, keyboard matrices, and test-equipment front-ends.
What package does the SN74HC165DR come in and what is the pin count?
The SN74HC165DR comes in a 16-pin SOIC (Small Outline Integrated Circuit) package with 1.27 mm (50 mil) lead pitch. The 'D' suffix denotes the SOIC-16 package and 'R' denotes tape-and-reel packaging with 2500 pieces per reel.
What are good substitutes or alternatives to the SN74HC165DR?
Pin-compatible alternatives include the SN74HC165N (DIP-16 through-hole version), 74HC165D from NXP, MM74HC165N from ON Semiconductor, and the SN74HCT165DR (TTL-compatible input thresholds for mixed 3.3 V/5 V systems). All are functionally identical 8-bit parallel-in serial-out shift registers.
Is the SN74HC165DR RoHS compliant?
Yes. The SN74HC165DR is fully RoHS compliant and lead-free (Pb-free). The 'R' suffix confirms it ships on tape-and-reel with green/halogen-free packaging per TI's standard eco-design requirements.
