CY74FCT2373TQCT

Latches Overview

The CY74FCT2373TQCT is an octal D-type transparent latch manufactured by Texas Instruments, featuring tri-state outputs. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 2 ns. The device provides high drive capability with output currents of 32 mA (high) and 64 mA (low). It is housed in a 20-SSOP package and functions reliably across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal configuration with eight independent data latches
• Tri-state outputs for bus-oriented memory operations
• Fast switching speed with 2 ns propagation delay
• High current drive capability for direct interface to CMOS, NMOS, and TTL loads

Latches Applications

• Bus-oriented memory register implementations
• I/O port buffering and latching circuits
• Clocked data storage in digital systems
• Parallel-to-serial conversion interfaces

Latches Procurement Notes

Verify the specific suffix 'QCT' corresponds to the 20-SSOP tape-and-reel packaging format required for your assembly process. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements against your manufacturing standards before ordering. Ensure the supplier provides valid traceability documentation for this Texas Instruments component.

Latches Selection Notes

Select this component when an octal latch with tri-state control is required for high-speed data retention. The FCT series offers bipolar-compatible speeds with CMOS power consumption. Consider the 20-SSOP package constraints and thermal characteristics if operating near the upper temperature limit of 85°C.

Latches Part Context

This part belongs to the Texas Instruments CY74FCT logic family, designed for high-speed applications. It serves as a functional equivalent to older bipolar logic families while maintaining lower power dissipation typical of CMOS technology. The device is part of a broader portfolio of FCT-based registers and latches.

Latches Replacement Considerations

Direct substitutes include the CY74FCT2373T and CY74FCT2373TQ. Verify pinout compatibility and electrical specifications such as propagation delay and output current drive capabilities before substituting.
