MC74ACT373NG

Latches Overview

The MC74ACT373NG is an octal transparent latch with 3-state outputs, part of the onsemi MC74AC/ACT series. It features eight D-type latches in a single package, designed for bus-organized system applications. The device operates with TTL-compatible inputs and provides high drive capability, sourcing and sinking up to 24 mA. It supports supply voltages from 4.5 V to 5.5 V, ensuring compatibility with standard logic families while maintaining robust performance across industrial temperature ranges.

Latches Feature Summary

• Contains eight independent D-type latches within a single integrated circuit package
• Features 3-state outputs that facilitate direct interfacing with system buses
• Includes TTL-compatible input thresholds for seamless integration with legacy logic systems
• Provides strong output drive capabilities suitable for driving multiple loads

Latches Applications

• Bus-oriented memory systems requiring data storage and buffering
• Digital signal processing interfaces needing temporary data holding
• Microprocessor-based systems utilizing parallel data transfer architectures
• Industrial control panels managing multiple input/output states

Latches Procurement Notes

Verify the specific ordering suffix (e.g., DWG for SOIC-20) matches the required package type and lead-free status. Confirm the voltage grade corresponds to the ACT variant for TTL compatibility. Ensure the procurement channel sources genuine onsemi components to guarantee reliability and adherence to specified electrical characteristics. Check for moisture sensitivity level requirements during storage and handling.

Latches Selection Notes

Select the MC74ACT373 when TTL-compatible inputs are necessary alongside AC-speed performance. Choose this component over the standard AC version if interfacing directly with 5V TTL logic without level shifting. Consider the 3-state output feature for bus sharing applications. Evaluate the package options based on board space constraints and thermal management needs.

Latches Part Context

This component belongs to the MC74AC/ACT family of octal latches. It shares functional similarities with other devices in the series but is distinguished by its ACT designation, which ensures TTL input compatibility. The family is widely used in digital electronics for data storage and bus interface applications, offering a balance of speed and drive strength.

Latches Replacement Considerations

Direct substitutes include the MC74AC373 for non-TTL input applications or other octal latches with 3-state outputs from compatible manufacturers. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement device meets the same voltage and current requirements.
