CY74FCT2373CTSOCT

Latches Overview

The CY74FCT2373CTSOCT is an octal D-type transparent latch with 3-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. The device features a 20-pin SOIC package and operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.7 ns at 5 V, a low-level output current of 32 mA, and a high-level output current of -15 mA. It functions as a single circuit with eight input and eight output lines, maintaining non-inverting polarity.

Latches Feature Summary

• Provides octal data storage with transparent latch functionality for efficient bus interfacing
• Integrates 3-state outputs to facilitate direct connection to system buses without external drivers
• Features internal 25-ohm output series resistors designed to reduce transmission-line reflection noise

Latches Applications

• Parallel data buffering in high-speed digital systems
• Bus-oriented memory register implementations
• Clock domain crossing synchronization circuits

Latches Procurement Notes

Verify the specific suffix 'CTSOCT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure compatibility with existing PCB footprints for the 20-SOIC package. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with high drive capability and noise immunity. The FCT series offers performance comparable to bipolar logic while maintaining CMOS power efficiency. Consider the 4.7 ns propagation delay and 32 mA output drive strength for timing-critical applications operating at 5 V.

Latches Part Context

This part is part of the CY74FCT2373T family of octal latches. It is functionally compatible with other fast CMOS logic families, allowing for mixed-logic designs. The device is optimized for applications demanding high-speed data transfer and reliable latching behavior in industrial and commercial environments.

Latches Replacement Considerations

Check for pin-compatible alternatives within the same FCT family or equivalent parts from other manufacturers that meet the 20-SOIC package and 5V logic requirements. Verify that any substitute maintains the 3-state output capability and similar propagation delay specifications.
