CD74HC670MT

Overview

The CD74HC670MT is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as a 4-by-4 register file. It operates within a supply voltage range of 2 V to 6 V and supports a propagation delay of 295 ns. The device features four input lines and four output lines, housed in a 16-SOIC surface-mount package. It is rated for an operating temperature range from -55 °C to +125 °C, with low-level and high-level output currents specified at 7.8 mA.

Feature Summary

• High-speed CMOS technology enables efficient data storage and transfer operations.
• Integrated 4-by-4 register file architecture provides dedicated parallel data handling capabilities.
• Wide operating voltage range supports flexible integration across various digital systems.

Applications

• Parallel data buffering in digital communication interfaces
• Temporary storage in microprocessor-based control systems
• Data routing and switching in logic circuit designs

Procurement Notes

Verify the specific suffix 'M' indicates the SOIC-16 surface-mount package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified -55 °C to +125 °C operating range for reliable performance in industrial environments.

Selection Notes

Select this component when a compact, high-speed 4-bit register file is required for surface-mount applications. Compare against the CD74HCT670 series if TTL-compatible input levels are necessary instead of standard CMOS thresholds. Evaluate package constraints to ensure the 16-SOIC footprint fits the target PCB layout requirements.

Part Context

This part belongs to the Texas Instruments CD74HC670 family of high-speed CMOS logic devices. It serves as a specialized register file solution within the broader 74HC logic series, designed for applications requiring fast parallel data storage and retrieval without the complexity of general-purpose shift registers or memory arrays.
