74F373SC

Latches Overview

The Fairchild Semiconductor 74F373SC is an octal transparent latch featuring three-state outputs, designed for bus-oriented system applications. It belongs to the F/FAST logic series and operates with a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-lead Small Outline Integrated Circuit (SOIC) package, specifically identified as MS-012 with a 0.150-inch width. It provides eight latches within a single integrated circuit, ensuring data retention when the Latch Enable input transitions from high to low.

Latches Feature Summary

• Incorporates eight D-type latches in a single package for efficient data storage
• Features three-state outputs to facilitate direct interfacing with system buses
• Provides guaranteed minimum ESD protection of 4000V

Latches Applications

• Bus-oriented system data storage
• System interface modules requiring tri-state control
• Digital logic circuits utilizing F/FAST series components

Latches Procurement Notes

Verify the specific manufacturer origin, as the 74F373SC designation may be produced by multiple vendors including Fairchild, National Semiconductor, or Nexperia. Confirm that the SOIC-20 package dimensions match the MS-012 standard. Ensure the component meets the required operating temperature range and voltage specifications for the target application before procurement.

Latches Selection Notes

Select this component for designs requiring high-speed octal latching with bus isolation capabilities. The F/FAST series offers performance characteristics suitable for systems demanding rapid data transfer. Consider the physical package constraints of the 20-lead SOIC form factor during PCB layout. Verify compatibility with existing logic families if interfacing with other TTL-compatible devices.

Latches Part Context

This component is part of the broader 74F373 family of octal transparent latches. Variants such as the SN74F373N or MM74HC373 offer similar functionality but differ in logic family technology, package type, or drive strength. The 74F373SC specifically denotes the small-outline package configuration within the F-series product line.

Latches Replacement Considerations

Direct substitutes include the SN74F373NSR and 74ACT373MTCX. Verify pinout compatibility and electrical parameters such as propagation delay and output current when replacing with these alternatives.
