CD74FCT373ATM

Latches Overview

The CD74FCT373ATM is an octal transparent latch manufactured by Harris Corporation, belonging to the FCT logic series. It features true outputs and operates with a CMOS technology base. The device is housed in a TSSOP-20 surface-mount package. It provides three-state output control for bus driving applications. The component supports standard voltage operation levels typical for the FCT family.

Latches Feature Summary

• Octal transparent latch architecture with eight D-type inputs
• Three-state outputs for effective bus line driving
• Bus hold inputs to eliminate external pull-up resistor requirements
• CMOS construction ensuring low power consumption

Latches Applications

• High-speed data latching in digital systems
• Bus driver interfaces requiring three-state control
• Memory address register storage
• I/O port buffering for microprocessor systems

Latches Procurement Notes

Verify the manufacturer origin as Harris Corporation or authorized successor entities like Texas Instruments, as production rights may have transferred. Confirm the specific suffix 'ATM' corresponds to the TSSOP-20 package and temperature rating. Check RoHS compliance status, as older Harris FCT parts may not meet current environmental standards. Ensure the source document explicitly lists this part number to avoid confusion with similar HC or HCT variants.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for high-speed CMOS applications. The FCT series offers faster propagation delays compared to standard HC or HCT logic families. Consider the TSSOP-20 package size for space-constrained surface-mount designs. Verify input compatibility with the system's logic voltage levels before integration.

Latches Part Context

This component is part of the Harris FCT (Fast CMOS) logic family, designed for high-speed digital applications. The FCT series bridges the performance gap between standard CMOS and LSTTL technologies. Harris Corporation was a primary manufacturer of these logic ICs before industry consolidations. The CD74 prefix indicates commercial temperature range availability.
