CD74HC670M96

Overview

The CD74HC670M96 is a high-speed CMOS logic device functioning as a 4-by-4 register file, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 295 ns. The component supports low-level output currents of 7.8 mA and high-level output currents of -7.8 mA. Designed for surface-mount installation, it utilizes an SOIC-16 package. The device is rated for operation across an extended temperature range from -55°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

• High-speed CMOS technology enables efficient data storage and retrieval operations.
• Integrated 4-by-4 register file architecture provides dedicated parallel data handling capabilities.
• Extended industrial temperature rating ensures stable performance under varying thermal conditions.

Applications

• Parallel data buffering in digital signal processing systems
• Address register storage in microprocessor-based interfaces
• Data latching in high-speed communication protocols

Procurement Notes

Verify the specific suffix M96 corresponds to the required tape-and-reel packaging configuration. Confirm that the SOIC-16 footprint matches the target PCB design constraints. Ensure the operating voltage requirements align with the 2 V to 6 V specification range. Validate compliance with RoHS directives if environmental standards are mandatory for the final assembly process.

Selection Notes

Select this component when a compact 4-bit wide by 4-deep memory structure is required within a single integrated circuit. The HC series offers compatibility with standard CMOS logic levels while providing sufficient drive current for moderate loads. Consider the 295 ns delay when designing timing-critical paths. The wide voltage range allows flexibility in power supply design compared to fixed-voltage logic families.

Part Context

This part belongs to the Texas Instruments CD74HC670 series of high-speed CMOS logic devices. The series focuses on providing versatile register files for digital applications. The M96 suffix typically denotes specific packaging and handling characteristics distinct from other variants in the same logical family, such as those in tube or different reel configurations.

Replacement Considerations

Consult official substitution guides for equivalent 4x4 register files from the same manufacturer. Verify pinout compatibility before replacing with alternative logic families. Ensure electrical parameters like propagation delay and output current meet system requirements when considering cross-brand alternatives.
