CD74HCT670M96G4

Overview

The CD74HCT670M96G4 is a high-speed CMOS logic register file manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 295 ns. The device supports four input lines and four output lines, housed in a 16-pin SOIC-Narrow package. It functions as a single circuit with an operating temperature range from -55 °C to +125 °C.

Feature Summary

• High-speed CMOS technology for efficient digital processing
• Register file architecture supporting 4-by-4 data handling
• Wide industrial operating temperature range for harsh environments

Applications

• Digital signal processing systems requiring temporary data storage
• Computer memory interface circuits
• Industrial control logic applications

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status when ordering. Confirm the SOIC-Narrow package dimensions match the target PCB footprint. Ensure the 4.5 V to 5.5 V supply voltage aligns with the system design requirements before procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS outputs. The HCT series ensures compatibility with standard TTL logic levels. Verify that the 295 ns propagation delay meets the timing constraints of the target application circuit.

Part Context

This part belongs to the Texas Instruments CD74HCT670 family of high-speed CMOS logic devices. It serves as a specialized register file within the broader logic IC portfolio. The device integrates multiple logic gates into a single functional unit for data storage operations.

Replacement Considerations

CD74HC670M96 offers similar functionality but requires a wider voltage range. CD74HCT670E provides equivalent performance in a PDIP package. Verify pinout compatibility before substituting these alternatives.
