74ABT573CMTCX

Latches Overview

The Fairchild Semiconductor 74ABT573CMTCX is an octal D-type transparent latch featuring buffered common Latch Enable (LE) and Output Enable (OE) inputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides tri-state outputs capable of sourcing up to 32 mA and sinking up to 64 mA. It utilizes a 20-pin TSSOP surface-mount package and supports operation temperatures from -40°C to +85°C.

Latches Feature Summary

• Octal D-type transparent latch architecture with buffered control inputs
• Tri-state outputs designed for efficient bus interfacing applications
• High current drive capability supporting robust load conditions

Latches Applications

• Microprocessor input or output port interfacing
• Bus driver circuits requiring high-speed data latching
• Memory address register implementations

Latches Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot codes against current datasheet requirements. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity and performance specifications.

Latches Selection Notes

Select this component when an octal latch with tri-state outputs is required for 5V logic systems. The ABT series offers superior speed compared to standard AC/ACT families. Verify that the TSSOP-20 package fits the PCB layout constraints and that the 5V operating voltage aligns with the system power supply design.

Latches Part Context

This part belongs to the 74ABT logic family, known for high-speed CMOS technology. It is functionally similar to the 74ABT373 but features inputs and outputs on opposite sides of the package, facilitating easier interface with microprocessors. The CMTCX suffix indicates the specific TSSOP-20 packaging and reel configuration.

Latches Replacement Considerations

The 74ABT373CMTCX serves as a functional substitute, though pinout orientation differs. The 74ACT573MTC is compatible for lower-speed applications. Verify package compatibility and electrical parameters before substitution.
