CD74FCT373ATM96

Latches Overview

The CD74FCT373ATM96 is an octal transparent D-type latch manufactured by Harris Corporation. It features eight D-type latches with three-state outputs, designed for high-speed bus-oriented memory mapping and driving applications. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes FCT CMOS technology. It is housed in a 20-pin SOIC surface-mount package (PDSO20). Key electrical characteristics include a typical propagation delay of 12ns at VCC=5V and CL=15pF, with a load capacitance rating of 50 pF. The component supports an operating temperature range from -40°C to 85°C.

Latches Feature Summary

• Octal transparent latch configuration with common latch enable control
• Three-state outputs providing bus line driving capacity
• Direct compatibility with LSTTL logic levels via HCT/FCT interface standards
• Bus hold inputs eliminate the need for external pull-up resistors

Latches Applications

• Bus-oriented memory mapping systems
• Driving bus lines in high-speed digital circuits
• Parallel data storage and transfer interfaces

Latches Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'TM96' corresponds to the tape and reel packaging format and ensure the RoHS status aligns with project requirements, as older FCT series parts may not be compliant. Cross-reference the datasheet revision to confirm pinout and electrical specifications match the design intent.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus interfacing. It is suitable for designs needing direct LSTTL input compatibility without level shifting. Consider the SOIC-20 package constraints and the 4.5V to 5.5V supply voltage requirement. Ensure the application does not require RoHS compliance if sourcing original Harris stock.

Latches Part Context

This part belongs to the CD74FCT series of high-speed CMOS logic devices. The FCT family offers performance comparable to LSTTL but with lower power consumption. The CD74FCT373 specifically provides octal latching functionality, distinguishing it from transceivers or drivers in the same series. It is functionally compatible with standard 74LS373 pinouts.

Latches Replacement Considerations

CD74FCT373ATE: DIP-20 variant with similar electrical characteristics. CD74FCT373AT: SOIC-20 variant without the specific TM96 tape/reel suffix. Verify that substitute packages meet mechanical board space requirements.
