CY74FCT373CTSOC

Latches Overview

The CY74FCT373CTSOC is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features non-inverting polarity and provides eight input lines corresponding to eight output lines. It exhibits a propagation delay of 5.2 ns at 5 V, with low-level output current capability of 32 mA and high-level output current of -32 mA. The component supports surface mount installation in a QSOP-20 package and functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with tri-state output control
• High-speed data storage with 5.2 ns propagation delay at 5 V
• Robust drive capability supporting 32 mA sink and source currents
• Extended industrial temperature operation from -40°C to +85°C

Latches Applications

• Parallel data buffering in high-speed digital systems
• Interface bridging between microprocessors and peripheral devices
• Temporary data storage in register file architectures
• Bus holding applications requiring tri-state isolation

Latches Procurement Notes

Verify the specific suffix CT against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts for the QSOP-20 footprint. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference ordering information directly with manufacturer catalogs to avoid substitution errors.

Latches Selection Notes

Select this component when designing systems requiring octal latching with high drive strength and fast switching speeds. The FCT series offers CMOS compatibility with TTL-like performance characteristics. Consider the QSOP-20 package constraints regarding thermal dissipation and pin pitch. Evaluate power supply stability requirements given the 4.75 V to 5.25 V operational window.

Latches Part Context

This part is part of the CY74FCT373T family of octal latches. It shares functional similarities with other FCT series components but differs in packaging and specific electrical tolerances. The CY74FCT373CTSOC represents a specialized variant optimized for surface-mount technology applications requiring reliable data retention in industrial environments.

Latches Replacement Considerations

Direct substitutes include CY74FCT373ATQCT and CY74FCT373TSOC. Verify pinout compatibility and electrical parameters before replacement. Ensure that alternative packages meet mechanical space requirements.
