CD74HC164ME4

Shift Registers Overview

The CD74HC164ME4 is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the HC logic family and utilizes high-speed silicon gate CMOS technology. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. It is housed in a 14-pin SOIC package. Key electrical parameters include a propagation delay of 170 ns, 34 ns, and 29 ns under varying conditions.

Shift Registers Feature Summary

• Converts serial data input into parallel output across eight bits
• Compatible with low-power Schottky TTL (LSTTL) logic levels
• Features push-pull outputs for improved drive capability

Shift Registers Applications

• Serial-to-parallel data conversion interfaces
• LED display matrix scanning systems
• General-purpose digital logic shifting operations

Shift Registers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific tape-and-reel packaging requirements if applicable. Ensure the part number suffix matches the intended package variant before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel output is required in a surface-mount design. Consider the HC series compatibility with standard logic families. Verify that the 14-pin SOIC footprint fits the PCB layout constraints and that the voltage range meets system power specifications.

Shift Registers Part Context

This part is part of the broader 74HC164 family of shift registers. It shares functional similarities with other 8-bit serial-in parallel-out devices but is distinguished by its specific Texas Instruments manufacturing process and HC logic characteristics. It serves as a fundamental building block for sequential logic circuits requiring data expansion.

Shift Registers Replacement Considerations

Direct substitutes may include equivalent 74HC164 variants from other manufacturers such as Nexperia or onsemi, provided pinouts and electrical characteristics match. Verify package dimensions and thermal performance when cross-referencing alternative sources.
