CD54HC164F

Shift Registers Overview

The CD54HC164F is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the high-speed CMOS (HC) logic family and operates within a supply voltage range of 2 V to 6 V. The device features two serial data inputs (A and B) that are internally ANDed, allowing for flexible input configurations. It includes a master reset input that asynchronously clears all eight flip-flops when driven low. The component is designed for military-grade reliability with an extended operating temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion using eight D-type flip-flops
• Features dual serial inputs (A and B) that are logically combined
• Includes an asynchronous master reset function to clear outputs
• Supports wide voltage operation suitable for diverse digital systems

Shift Registers Applications

• Military-grade digital signal processing circuits
• Industrial control systems requiring extended temperature stability
• Data acquisition systems utilizing serial communication interfaces
• Automotive electronics operating in harsh environments

Shift Registers Procurement Notes

Verify the specific suffix 'F' indicates ceramic packaging during procurement. Confirm the manufacturer's current production status as legacy components may face obsolescence. Ensure the supplier provides traceability documentation required for military or aerospace applications. Check for RoHS compliance if environmental regulations apply to the final assembly. Validate the package type matches the design constraints before ordering.

Shift Registers Selection Notes

Select this component when military-grade temperature ranges and radiation hardness are required. Compare against standard 74HC164 variants if commercial temperature ranges suffice. Consider the ceramic package size and weight constraints for the application. Evaluate power consumption differences between HC and HCT families if voltage levels vary. Verify pin compatibility with existing PCB layouts if replacing older designs.

Shift Registers Part Context

This part is part of the CD54/74HC series of high-speed CMOS logic devices. The CD54 prefix denotes military-grade qualification, distinguishing it from the commercial CD74 series. It serves as a fundamental building block for sequential logic circuits in robust electronic systems. The device complements other logic gates and memory elements within the same family.

Shift Registers Replacement Considerations

CD74HC164M is a commercial-grade equivalent with similar electrical characteristics but limited temperature range. SN54HC164J offers alternative packaging options within the military grade line. Verify pinout compatibility and voltage thresholds when substituting with non-TI manufacturers.
