CD74HC670E

Overview

The CD74HC670E 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 up to 7.8 mA and high-level output currents of -7.8 mA. Designed for robust performance, it withstands operating temperatures from -55 °C to +125 °C. The device is housed in a PDIP-16 package, providing four input lines and four output lines for data handling.

Feature Summary

• Implements a 4-by-4 register file architecture using high-speed CMOS technology
• Provides asynchronous reset functionality for immediate state clearing
• Supports wide industrial temperature ranges for reliable operation

Applications

• Data storage and buffering in digital logic circuits
• Register file implementation in microprocessor systems
• Temporary data holding in high-speed communication interfaces

Procurement Notes

Verify the specific package type and suffix against official Texas Instruments documentation before procurement. Ensure that the ordering information matches the required pin configuration and electrical specifications. Confirm RoHS compliance status and manufacturing origin details directly with authorized distributors or the manufacturer's official channels to guarantee part authenticity and specification accuracy.

Selection Notes

Select this component when a compact 4-by-4 register file solution is required within HC series logic families. Consider the PDIP-16 through-hole package for prototyping or applications requiring manual assembly. Evaluate the 295 ns propagation delay against system timing requirements to ensure compatibility with clock speeds. Verify power supply constraints align with the 2 V to 6 V operational range.

Part Context

This device belongs to the Texas Instruments CD74HC series, which utilizes complementary metal-oxide-semiconductor technology for high-speed digital operations. The HC series is designed to be compatible with previous 74LS logic standards while offering improved speed and lower power consumption. Register files in this family facilitate efficient data management in complex digital systems.

Replacement Considerations

Consult official substitution guides for equivalent parts. Cross-reference pinouts and electrical characteristics carefully.
