SN74HC165PWRG4

Shift Registers Overview

The SN74HC165PWRG4 is an 8-bit parallel-load shift register from the Texas Instruments SN74HC165 series. It utilizes CMOS logic technology and operates within a supply voltage range of 2 V to 6 V. The device features serial/parallel-to-serial counting order and includes a parallel enable input for data loading. It is housed in a TSSOP-16 surface-mount package and supports positive-edge triggering. The component functions as a single circuit with nine input lines and one output line, designed for standard industrial operating temperatures between -40°C and +125°C.

Shift Registers Feature Summary

• Supports simultaneous parallel data loading via dedicated inputs
• Converts parallel input data into a serial output stream
• Operates on positive-edge triggered clock signals

Shift Registers Applications

• Digital data acquisition systems requiring parallel-to-serial conversion
• Microcontroller interface expansion for multiple input devices
• Keyboard matrix scanning circuits

Shift Registers Procurement Notes

Verify the specific suffix G4 indicates lead-free packaging compliant with RoHS standards. Confirm the TSSOP-16 package dimensions match the target PCB footprint. Ensure the voltage supply aligns with the 2 V to 6 V operational range. Check that the temperature rating meets environmental requirements. Validate the manufacturer part number against official Texas Instruments documentation.

Shift Registers Selection Notes

Select this component when an 8-bit parallel load capability is required alongside serial output functionality. The HC logic family offers compatibility with standard 5 V and 3.3 V logic levels. Consider the TSSOP-16 package for space-constrained surface mount designs. Verify that the propagation delay characteristics suit the system timing constraints.

Shift Registers Part Context

This part belongs to the SN74HC165 family of 8-bit parallel-load shift registers manufactured by Texas Instruments. The HC designation identifies it as high-speed CMOS logic. The G4 suffix typically denotes a lead-free and environmentally friendly variant. It serves as a digital logic IC within the broader category of counter shift registers.

Shift Registers Replacement Considerations

SN74HC165PWR is a compatible alternative within the same series offering identical logical functionality.
