74VHCT373AM

Latches Overview

The onsemi 74VHCT373AM is an octal D-type latch with 3-STATE outputs manufactured using silicon gate CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. The device features a typical propagation delay of 7.7ns at 25°C and maintains a maximum quiescent supply current of 4µA. It utilizes a 20-Lead Small Outline Integrated Circuit (SOIC) package.

Latches Feature Summary

• High-speed operation comparable to Bipolar Schottky TTL while maintaining low power dissipation
• Power-down protection provided on all inputs and outputs for safe interfacing between mismatched supply voltages
• Pin and function compatible with standard 74HCT373 devices

Latches Applications

• Interface circuits connecting 3V to 5V systems
• Battery backup system data storage
• Parallel data buffering in digital logic designs

Latches Procurement Notes

Verify the manufacturer origin, as this component was originally developed by Fairchild Semiconductor. Confirm that the specific ordering suffix matches the required SOIC package dimensions and pinout configuration. Ensure compliance with RoHS standards if applicable to the target assembly process.

Latches Selection Notes

Select this component when high-speed latching is required alongside low static power consumption. It is suitable for applications needing direct compatibility with existing 74HCT373 footprints without redesigning the PCB layout or signal integrity parameters.

Latches Part Context

This part belongs to the VHCT373A family of octal D-type latches. It represents an advanced CMOS solution designed to bridge the performance gap between traditional HCT logic families and modern low-power requirements, offering robust noise immunity and fast switching speeds.
