74VHCT374M

Overview

The onsemi 74VHCT374M is a high-speed CMOS octal D-type flip-flop featuring three-state outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 130 MHz. The device exhibits a maximum propagation delay of 20ns at 5V with a 50pF load. It contains eight non-inverting D-type elements in a single package, housed in a 20-SOIC surface-mount enclosure. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• High-speed operation enabled by silicon gate CMOS technology
• Three-state outputs allow direct bus line connections
• Non-inverting logic polarity for straightforward signal routing

Applications

• Parallel-to-serial data conversion circuits
• Buffering and register applications in digital systems
• Clocked memory interface designs

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet before procurement. Confirm RoHS compliance status as legacy variants may differ. Ensure the 20-SOIC package dimensions match the target PCB footprint requirements. Check for obsolescence notices or lifecycle changes directly from onsemi documentation prior to finalizing orders.

Selection Notes

Select this component when high-speed clocking up to 130 MHz is required with standard 5V logic compatibility. The VHCT series ensures TTL-compatible input thresholds while maintaining CMOS output drive capabilities. Consider the 20-SOIC package for surface-mount assembly needs. Evaluate power consumption and thermal dissipation characteristics relative to the system's overall heat budget and ambient operating conditions.

Part Context

This part belongs to the 74VHCT logic family, designed for high-speed applications requiring TTL-compatible inputs. It serves as an octal D-type flip-flop with three-state outputs, distinct from standard 74HC or 74HCT variants by its enhanced speed performance. The component integrates eight independent flip-flops into a single integrated circuit package for compact digital design solutions.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include MC74VHCT374ADWR2G and MC74VHCT374ADWRG from onsemi. Cross-manufacturer alternatives such as SN74AHCT374DW and SN74AHCT374DWR from Texas Instruments are also listed as compatible options.
