MC74HC573ADTR2G-Q

Latches Overview

The MC74HC573ADTR2G-Q is an octal 3-state noninverting transparent latch in a TSSOP-20 package. It operates within a 2.0 V to 6.0 V supply range with low input current and high noise immunity. The device features outputs directly interfacing to CMOS, NMOS, and TTL loads. It includes latch enable and output enable controls for data transparency and high-impedance states.

Latches Feature Summary

• Transparent latch functionality where outputs change asynchronously when Latch Enable is high
• Data latching occurs when Latch Enable transitions low, capturing meeting setup and hold time data
• Outputs provide three-state control via Output Enable for bus driving applications
• Inputs compatible with standard CMOS outputs and LSTTL outputs using pullup resistors

Latches Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Bus-oriented memory and register drives
• Two-line bidirectional data transmission
• Parallel I/O expansion in industrial control systems

Latches Procurement Notes

Verify the -Q suffix indicates automotive qualification and unique site requirements. Confirm PPAP capability if required by specific manufacturing standards. Ensure the TSSOP-20 package matches PCB footprint specifications. Check RoHS compliance status for environmental regulations. Validate operating temperature range against system thermal constraints.

Latches Selection Notes

Select this component for designs requiring octal latching with 3-state outputs. Consider the HC logic family for wide voltage operation between 2.0 V and 6.0 V. Evaluate propagation delay characteristics relative to system clock speeds. Assess power dissipation limits under maximum load conditions. Verify compatibility with existing CMOS or TTL interface levels.

Latches Part Context

This part belongs to the MC74HC573A series of octal transparent latches. It shares pinout compatibility with LS573 devices. The -Q suffix denotes automotive-grade qualification with controlled manufacturing sites. It complements other 74HC logic families for complex digital circuit implementations.

Latches Replacement Considerations

MC74HC573ADTR2G serves as the standard commercial equivalent without automotive qualification.
