Applications
The SN74LV165APW is widely used in microcontroller-based systems to expand digital input capacity by converting parallel data from switches, sensors, or GPIO pins into a serial stream. It is ideal for keyboard scanning, data acquisition front-ends, and industrial control interfaces where multiple input signals must be serialized over a limited number of communication lines. The device also fits embedded designs requiring SPI-compatible shift register chains for daisy-chained expansion.

Frequently Asked Questions
What is the maximum operating frequency of the SN74LV165APW?
The SN74LV165APW supports a maximum clock frequency of 35 MHz at nominal supply voltage with a 50 pF load capacitance, making it suitable for high-speed serial data conversion in embedded and communication systems.
What are the typical applications of the SN74LV165APW shift register?
Typical applications include parallel-to-serial data conversion for microcontroller input expansion, keyboard matrix scanning, industrial sensor interfaces, SPI bus expansion, and daisy-chained shift register configurations in embedded systems requiring multiple digital inputs over minimal I/O lines.
What package type does the SN74LV165APW come in?
The SN74LV165APW is packaged in a 16-pin SSOP small outline package (JESD-30 code R-PDSO-G16), which offers a compact PCB footprint suitable for space-constrained designs. It meets JESD-609 e4 environmental standards.
Can the SN74LV165APW be used as a replacement for 74HC165 or 74HCT165 devices?
The SN74LV165APW belongs to the LV/LV-A/LVX logic family and operates at lower supply voltages compared to 74HC165. Pin-compatible alternatives exist within the TI portfolio, but verify supply voltage and logic-level compatibility before substituting in existing designs.
