MC74VHC573DTR2G

Latches Overview

The MC74VHC573DTR2G is an octal D-type latch with 3-state outputs manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and supports surface-mount TSSOP-20 packaging. The device features high-speed operation with typical propagation delays of 4.5 ns at 5.0 V, low power dissipation with maximum quiescent current of 4.0 µA, and balanced propagation delays. It provides robust noise immunity and includes power-down protection.

Latches Feature Summary

• Octal transparent latch functionality with three-state output control
• High-speed CMOS technology enabling performance comparable to Bipolar Schottky TTL
• Power-down protection circuitry to prevent device destruction during supply mismatches
• Robust ESD protection exceeding 2000 V via Human Body Model testing

Latches Applications

• Parallel data storage in digital systems
• Bus-oriented memory applications
• Clocked register designs
• I/O buffering for microprocessor-based systems

Latches Procurement Notes

Verify the specific ordering suffix 'DTR2G' corresponds to the TSSOP-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance and lead-free status requirements align with project specifications. Ensure input pins are tied to appropriate logic levels when unused to maintain functional integrity.

Latches Selection Notes

Select this component for applications requiring high-speed data latching with low power consumption. The VHC series offers wider operating voltage ranges compared to standard HC logic. Verify that the 3-state output capability meets bus isolation requirements. Consider thermal resistance characteristics if operating near maximum temperature limits.

Latches Part Context

This part belongs to the MC74VHC573 family of advanced high-speed CMOS octal latches. It is functionally compatible with other standard logic families while maintaining CMOS low power dissipation. The device is designed for 2.0 V to 5.5 V operation, providing flexibility in system voltage architectures.

Latches Replacement Considerations

MC74VHCT573ADTR2G serves as a pin-compatible alternative with TTL-compatible inputs suitable for 5.0 V systems.
