CD74HCT670MTG4

Overview

The CD74HCT670MTG4 is a high-speed CMOS logic component manufactured by Texas Instruments, belonging to the 74HCT series. It functions as a 4-by-4 register file housed in a 16-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. Key electrical characteristics include a propagation delay of 295 ns, with low-level output current capability of 6 mA and high-level output current of -6 mA. This part is RoHS compliant and lead-free.

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status per manufacturer documentation. Confirm the SOIC-16 package dimensions match PCB footprint requirements. Ensure supply voltage constraints align with system design limits. Check for end-of-life notices or alternative recommendations from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a 4-bit wide, 4-deep register file is required in a high-speed CMOS environment. The HCT logic level ensures compatibility with TTL-driven systems while maintaining CMOS noise immunity. Consider the 295 ns propagation delay against system timing requirements. Verify that the 16-pin SOIC package fits the available board space and thermal management strategy.

Part Context

This component is part of the Texas Instruments 74HCT logic family, designed for high-speed applications requiring CMOS performance with TTL-compatible inputs. The 74HC670 series provides register file functionality, allowing for parallel data storage and retrieval. The 'M' designation indicates the SOIC package type, while 'G4' specifies environmental compliance attributes defined by the manufacturer.
