74LVTH573MTCX

Latches Overview

The Fairchild Semiconductor 74LVTH573MTCX is an octal transparent latch belonging to the LVTH logic series. It features eight D-type latches with three-state outputs in a 20-pin TSSOP package. The device operates within a supply voltage range of 2.7 V to 3.6 V, supporting high-speed data transfer with propagation delays of 4.9 ns at 2.7 V and 4.4 ns at 3.3 V. It provides strong drive capabilities with output currents up to 32 mA and low static power consumption.

Latches Feature Summary

• Octal configuration providing eight independent transparent latches for parallel data storage
• Three-state outputs allowing direct connection to bus structures without external drivers
• High-drive capability suitable for driving capacitive loads and transmission lines
• Low static power dissipation characteristic of CMOS technology

Latches Applications

• Parallel data buffering in microprocessor-based systems
• I/O port expansion for digital control applications
• Temporary data storage in communication interfaces
• Bus-oriented memory register implementations

Latches Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free soldering requirements against project specifications. Check for obsolescence notices as this part may be subject to discontinuation. Ensure proper ESD handling procedures during storage and assembly to prevent damage to sensitive CMOS inputs.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state bus compatibility. The LVTH series offers a balance between speed and drive strength compared to standard LVX logic. Verify that the 2.7 V to 3.6 V operating range matches the system power supply. Consider the TSSOP-20 package constraints regarding PCB layout and thermal management for surface-mount assembly.

Latches Part Context

This device is part of the 74LVTH family of low-voltage CMOS logic ICs manufactured by Fairchild Semiconductor (now onsemi). The LVTH series combines the speed of LVC logic with higher drive current capabilities. Similar parts in the family include the 74LVTH574 flip-flop and 74LVTH575 latch, offering different output configurations while maintaining compatible electrical characteristics and pinouts.

Latches Replacement Considerations

Direct substitutes include the 74LVTH573MTC from other manufacturers adhering to the same JEDEC standards. Cross-reference with onsemi equivalents if Fairchild stock is unavailable. Verify pinout compatibility and electrical parameters before substitution. Note that some variants may have different suffix codes indicating packaging or temperature ranges.
