74VHCT373ASJ

Latches Overview

The onsemi 74VHCT373ASJ is an octal D-type latch with 3-STATE outputs fabricated using silicon gate CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features a propagation delay of 7.7ns typical at 25°C, with a maximum quiescent supply current of 4µA. It utilizes a 20-Lead Small Outline Package (SOP) conforming to EIAJ TYPE II standards.

Latches Feature Summary

• Provides high-speed operation comparable to Bipolar Schottky TTL while maintaining low power dissipation.
• Includes power-down protection on all inputs and outputs to prevent device destruction during mismatched supply voltages.
• Features high noise immunity with defined input voltage thresholds for reliable logic level detection.

Latches Applications

• Interfacing between 3V and 5V systems
• Battery backup system integration
• Data storage in digital circuits

Latches Procurement Notes

Verify the specific package designation 'ASJ' corresponds to the 20-Lead SOP variant as documented in the ordering information table. Confirm that the component status aligns with the datasheet revision history, noting potential obsolescence or manufacturer transitions associated with Fairchild Semiconductor products now under onsemi.

Latches Selection Notes

Select this component when pin and function compatibility with standard 74HCT373 devices is required alongside enhanced speed characteristics. Ensure the application environment remains within the specified 4.5V to 5.5V supply voltage limits and the -40°C to +85°C temperature range for optimal performance.

Latches Part Context

This part belongs to the VHCT373A series of octal D-type latches. It is designed to bridge the gap between traditional HCT logic families and higher-speed requirements. The ASJ suffix specifically identifies the surface-mount SOP package configuration provided by the manufacturer.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74HCT373 variants that maintain identical pinouts and electrical specifications. Verify package dimensions for the 20-Lead SOP form factor to ensure mechanical compatibility during replacement.
