74FCT373CTQG

Latches Overview

The IDT 74FCT373CTQG is an octal transparent D-type latch manufactured by Integrated Device Technology. It features tri-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device utilizes FCT logic series technology and is housed in a 20-pin QSOP package. It supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include 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 draws a typical operating supply current of 200 uA.

Latches Feature Summary

• Provides eight-bit data storage with transparent latching functionality for temporary data retention.
• Features tri-state outputs that allow direct connection to system buses without external buffers.
• Utilizes advanced CMOS technology to achieve high-speed operation with low power consumption.

Latches Applications

• Bus driver implementations in digital systems
• Memory address latching applications
• I/O port buffering and control

Latches Procurement Notes

Verify the manufacturer designation carefully, as this component may be listed under Renesas Electronics due to corporate acquisitions. Confirm the specific suffix 'CTQG' matches the required 20-pin QSOP package and industrial temperature grade. Ensure compatibility with existing PCB footprints and check for any recent product change notices or discontinuance notifications associated with the IDT logic portfolio before finalizing procurement plans.

Latches Selection Notes

Select this component when an octal latch with tri-state bus interface capabilities is required. It serves as a suitable replacement for older ABT functions in high-speed designs. Consider the 20-pin QSOP package constraints and verify that the 5V supply voltage aligns with the target system architecture. Evaluate the propagation delay specifications against the maximum clock frequencies of the connected circuitry to ensure timing compliance.

Latches Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed to offer performance comparable to TTL circuits while maintaining CMOS power efficiency. The 74FCT373 variant specifically provides octal configuration, making it distinct from hex or quad latch options. It is widely used in embedded systems requiring reliable data storage and bus isolation.

Latches Replacement Considerations

Public confirmed substitute part numbers include 74FCT373CTQG8 and IDT74FCT373CTQG8. Verify pinout compatibility and electrical specifications before substitution.
