MC74VHCT573AM

Latches Overview

The MC74VHCT573AM is an octal D-type transparent latch with 3-state outputs manufactured by onsemi. It operates within a voltage range of 4.5 V to 5.5 V and utilizes advanced high-speed CMOS technology. The device features TTL-compatible inputs, ensuring compatibility with standard logic families while maintaining low power dissipation characteristics. Key electrical parameters include a typical propagation delay of 7.7 ns at 5.0 V and a maximum static current of 4 μA. It provides balanced propagation delays and includes power-down protection on inputs and outputs.

Latches Feature Summary

• High-speed operation comparable to Bipolar Schottky TTL with low CMOS power dissipation
• TTL-compatible input thresholds for broad system integration
• Power-down protection provided on both inputs and outputs
• ESD performance exceeding 2000 V via Human Body Model

Latches Applications

• Bus-oriented memory mapping
• Register files
• I/O buffering

Latches Procurement Notes

Verify the specific suffix 'AM' against the official datasheet to confirm package type and temperature rating. Ensure RoHS compliance status matches project requirements. Confirm pinout compatibility with existing PCB layouts before procurement.

Latches Selection Notes

Select this component when high-speed data latching is required alongside low power consumption. The VHCT series offers speed advantages over standard HCT devices. Verify that the operating voltage range aligns with the system's 5 V supply rails.

Latches Part Context

This part belongs to the MC74VHCT573A family of octal latches. It is designed for applications requiring fast switching speeds without the high power draw of bipolar technologies. The device integrates 234 FETs and is available in lead-free packages.

Latches Replacement Considerations

Check for direct substitutes like MC74VHCT573ADTG or MC74VHCT573ADTR2G which share identical functionality but may differ in packaging or reel specifications.
