MM74C164M

Shift Registers Overview

The MM74C164M is an 8-bit serial-in parallel-out shift register belonging to the CMOS logic family. It features gated serial inputs and an asynchronous clear function, packaged in a standard 14-pin SOIC format.

Shift Registers Feature Summary

• CMOS technology provides wide supply voltage range and low power consumption
• Gated serial inputs allow complete control over incoming data entry
• Asynchronous clear resets the first flip-flop independently of the clock

Shift Registers Applications

• Data terminals
• Instrumentation
• Medical electronics
• Alarm systems

Shift Registers Procurement Notes

Verify the specific manufacturer prefix (MM vs DM) against current datasheets as Fairchild Semiconductor assets have transitioned. Confirm RoHS compliance status for the M suffix package variant. Ensure the component matches the original National Semiconductor or Fairchild specifications if used in legacy designs requiring exact pinout compatibility with standard 74 series devices.

Shift Registers Selection Notes

Select this component when a non-volatile storage solution is not required but serial-to-parallel conversion is necessary. The CMOS construction offers high noise immunity suitable for industrial environments. Verify that the operating temperature range meets the system requirements, as standard C-series parts typically operate within a commercial range.

Shift Registers Part Context

This device is part of the 74C logic family, designed for compatibility with standard 74 series pinouts while utilizing CMOS technology. It serves as a fundamental building block for digital systems requiring data shifting capabilities without the complexity of bidirectional operations found in other shift register families.
