MM74HCT164N

Shift Registers Overview

The MM74HCT164N is an 8-bit serial-in, parallel-out shift register belonging to the HCT series. It features true outputs and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes CMOS technology with TTL-compatible input levels. It is housed in a 14-pin PDIP package with a 0.300-inch width. The component supports an operating temperature range from -40°C to +85°C.

Shift Registers Feature Summary

• Provides eight parallel data outputs for simultaneous data retrieval
• Accepts serial data inputs through dedicated gated pins
• Includes an asynchronous master reset function to clear all outputs

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Digital display driver interfaces
• General-purpose logic shifting operations

Shift Registers Procurement Notes

Verify the manufacturer designation on the component marking against Rochester Electronics or Fairchild Semiconductor records. Confirm the package style matches the specified PDIP-14 physical dimensions. Ensure the date code aligns with current production batches if new stock is required. Check for lead-free compliance markings consistent with RoHS standards.

Shift Registers Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS power efficiency. The HCT series ensures direct interfacing with standard TTL logic families without additional level shifting components. Consider the PDIP package for through-hole prototyping or applications requiring manual insertion and replacement capabilities.

Shift Registers Part Context

This part belongs to the widely adopted 74-series logic family, specifically the high-speed CMOS variant with TTL-compatible inputs. It serves as a fundamental building block for digital systems requiring data storage and transfer between serial and parallel domains. The MM prefix typically indicates a specific manufacturing line or revision within the broader 74HCT164 product line.

Shift Registers Replacement Considerations

Direct substitutes include the NXP 74HCT164N and ON Semiconductor MC74HCT164AN. Verify pinout compatibility and electrical specifications before substitution.
