74F373SCX

Latches Overview

The Fairchild Semiconductor 74F373SCX is an octal transparent latch featuring three-state outputs, designed for bus-oriented system applications. It belongs to the F/FAST logic series and utilizes TTL technology. The device comprises eight latches within a single package, providing true output polarity. It operates with a standard 5V power supply and supports a maximum operating temperature of 70°C. The component is housed in a 20-pin Dual In-line Package (DIP) with a .3-inch body width. It includes guaranteed minimum ESD protection of 4000V.

Latches Feature Summary

• Eight latches integrated into a single package for compact design
• Three-state outputs facilitate direct interfacing with bus lines
• Transparent operation when Latch Enable input is HIGH
• High noise immunity characteristic of the F/FAST logic family

Latches Applications

• Bus-oriented system data storage
• Parallel register applications
• Interface between microprocessors and peripheral devices
• Data buffering in digital systems

Latches Procurement Notes

Verify the specific suffix 'SCX' against current manufacturer documentation to confirm exact packaging and lead-free status. Ensure compatibility with existing 5V logic levels and DIP-20 footprint requirements. Confirm RoHS compliance if required by project specifications, as older revisions may differ. Cross-reference ordering information with official Fairchild or onsemi catalogs to avoid obsolete part numbers.

Latches Selection Notes

Select this component when high-speed latching with bus isolation is required in TTL-compatible environments. The F/FAST series offers superior speed compared to standard LS logic while maintaining low power consumption relative to bipolar alternatives. Consider the 20-pin DIP form factor for through-hole assembly needs. Evaluate the 4000V ESD protection rating for robustness in high-interference environments.

Latches Part Context

This device is part of the widely used 74xx series of logic integrated circuits. Specifically, it falls under the F/FAST category, known for high-speed performance. Similar variants include the 74AC373 and 74ACT373, which offer different voltage ranges and speeds. The 74F373 serves as a fundamental building block for sequential logic circuits requiring parallel data retention and controlled output enablement.

Latches Replacement Considerations

Equivalent parts include the 74F373 from other manufacturers such as NXP or Nexperia. Verify pinout compatibility and electrical characteristics before substitution. Alternative packages like MSA or PC may be available depending on manufacturing preferences.
