74HCT164DB,112

Shift Registers Overview

The 74HCT164DB,112 is an 8-bit serial-in, parallel-out shift register manufactured by Nexperia USA Inc. It belongs to the 74HCT logic family and operates within a supply voltage range of 4.5 V to 5.5 V. The device features push-pull outputs and is housed in a 16-SSOP package. It supports a wide operating temperature range from -40°C to +125°C and complies with RoHS3 standards.

Shift Registers Feature Summary

• Converts serial input data into parallel output using two serial data inputs (A and B) and a clock input.

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Driving parallel loads such as LED displays or indicator arrays
• Expanding I/O capabilities for microcontrollers

Shift Registers Procurement Notes

Verify the specific suffix '112' against the manufacturer's current datasheet to confirm the 16-SSOP packaging and lead-free status. Confirm that the 74HCT variant matches the system's 5V logic requirements, as HC and HCT families have different input threshold characteristics. Check for any recent Product Change Notifications regarding assembly sites or marking updates.

Shift Registers Selection Notes

Select this component when a TTL-compatible 8-bit shift register is required for 5V applications. The HCT series ensures compatibility with standard TTL logic levels. Ensure the design accommodates the 16-pin SSOP footprint and verify that the maximum operating temperature of +125°C meets the environmental constraints of the target application.

Shift Registers Part Context

This part is part of the 74HCT164 family of shift registers. It shares functional similarities with other 8-bit shift registers but is distinguished by its HCT logic level compatibility and SSOP package option. It serves as a fundamental building block for sequential logic circuits requiring data serialization.

Shift Registers Replacement Considerations

MC74HC164ADG by onsemi is listed as a substitute. Verify if the HC logic level is acceptable for the specific circuit interface, as it differs from the HCT input thresholds of the original part.
