SN74HC165ANSR

Shift Registers Overview

The SN74HC165ANSR is an 8-bit parallel-load shift register from Texas Instruments, belonging to the 74HC logic family. It converts parallel data inputs into a serial output stream via a single pin. The device operates within a supply voltage range of 2 V to 6 V and features Schmitt-trigger inputs for noise immunity. It utilizes a 16-pin SOIC package suitable for surface-mount applications.

Shift Registers Feature Summary

• Parallel-to-serial data conversion capability with dedicated parallel load control
• Schmitt-trigger inputs provide enhanced noise filtering and signal integrity
• Compatible with standard CMOS logic families across a wide voltage range

Shift Registers Applications

• Expanding digital input capacity in microcontroller-based systems
• Keyboard matrix scanning interfaces
• Industrial control panel input monitoring

Shift Registers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the 16-SOIC package and tape-and-reel packaging format. Confirm RoHS compliance status and manufacturing origin details through official Texas Instruments documentation or authorized distributor datasheets prior to procurement.

Shift Registers Selection Notes

Select this component when parallel expansion is required for digital inputs using minimal I/O pins. Ensure the operating voltage aligns with the 2 V to 6 V specification. Consider the propagation delay characteristics relative to system clock speeds and verify package compatibility with existing PCB footprints.

Shift Registers Part Context

This part belongs to the SN74HC165 series of 8-bit parallel-load shift registers. It shares functional similarities with other HC-series logic devices but is optimized for high-speed CMOS operation. The series supports various package options including SOIC, TSSOP, and PDIP variants.

Shift Registers Replacement Considerations

SN74HC165DRG3: Pin-compatible alternative in SOIC-16 package. SN74HC165PWRG3: Alternative in TSSOP-16 package requiring footprint adjustment.
