SN74HC165PWRG3

Shift Registers Overview

The SN74HC165PWRG3 is an 8-bit parallel-load shift register from the Texas Instruments HC logic family. It converts eight parallel data inputs into a serial output stream, facilitating efficient data transmission in digital systems. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 25 MHz. It features a serial input for daisy-chaining multiple units and includes a complementary serial output. The component is housed in a 16-pin TSSOP package and is rated for operation across an extended temperature range of -40°C to +125°C.

Shift Registers Feature Summary

• Parallel-to-serial conversion capability with dedicated parallel load control
• Daisy-chainable architecture via serial input and complementary output pins
• High-speed CMOS technology ensuring low power consumption and fast switching

Shift Registers Applications

• Keyboard scanning circuits requiring multiple input polling
• Expansion of I/O ports in microcontroller-based embedded systems
• Data acquisition systems interfacing parallel sensors to serial buses

Shift Registers Procurement Notes

Verify the complete part number including the G3 suffix to ensure compliance with specific environmental standards such as RoHS and lead-free requirements. Confirm the TSSOP-16 package dimensions against your PCB footprint design. Check the datasheet for recommended soldering profiles and moisture sensitivity level handling procedures to prevent damage during assembly.

Shift Registers Selection Notes

Select this component when an 8-bit parallel interface must be reduced to a single serial line for communication with a host processor. Ensure the operating voltage aligns with the system's 2 V to 6 V range. Consider the HC series speed and drive capabilities relative to other logic families if higher fan-out or different voltage levels are required.

Shift Registers Part Context

This part belongs to the SN74HC165 family of 8-bit parallel-load shift registers manufactured by Texas Instruments. The 'PWR' designation indicates the TSSOP-16 surface-mount package, while 'G3' signifies green packaging compliant with RoHS standards and no antimony oxide content. It is functionally compatible with industry-standard 74HC165 devices.

Shift Registers Replacement Considerations

Compatible substitutes include SN74HC165DRG3 (SOIC-16 package) and SN74HC165PWR (standard TSSOP-16). Verify pin compatibility and electrical specifications before substitution.
