74LVC573AQ20-13

Latches Overview

The 74LVC573AQ20-13 is an octal transparent D-type latch with 3-state outputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 3.6V and features inputs tolerant to 5.5V for mixed-voltage compatibility. The device supports partial power-down applications via I_OFF circuitry, which disables outputs to prevent damaging backflow current. It includes Schmitt trigger action at all inputs and provides ESD protection exceeding 2000-V Human Body Model standards.

Latches Feature Summary

• Provides eight transparent D-type latches with buffered output-enable control
• Supports partial-power down operation through integrated I_OFF circuitry
• Features inputs tolerant to 5.5V for mixed-voltage system integration
• Includes Schmitt trigger action at all inputs to improve noise immunity

Latches Applications

• General purpose logic circuits
• Bus driving applications
• Power down signal isolation

Latches Procurement Notes

Verify the specific package code Q20 corresponds to the V-QFN4525-20 housing when sourcing this component. Confirm that the -13 suffix indicates tape and reel packaging quantities. Ensure compliance with RoHS directives and halogen-free requirements if environmental specifications are mandatory for the target assembly process.

Latches Selection Notes

Select this part when an octal latch configuration is required in a compact surface-mount footprint. The V-QFN4525-20 package offers a smaller profile compared to TSSOP alternatives. Consider the 5.5V input tolerance if interfacing with legacy 5V logic systems while operating the core at lower voltages.

Latches Part Context

This component belongs to the 74LVC573A series of low-voltage CMOS logic devices. It serves as the QFN-packaged variant within the broader family of octal transparent D-type latches. The series is designed for high-speed digital applications requiring low power consumption and robust performance across varying temperature ranges.

Latches Replacement Considerations

The 74LVC573AT20-13 is a direct functional substitute utilizing a TSSOP-20 package instead of the V-QFN4525-20 housing.
