74LVT573PW,112

Latches Overview

The 74LVT573PW,112 is an octal D-type transparent latch with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.7 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes a TSSOP-20 surface-mount package and supports bus-oriented applications through common output enable control. It includes I_OFF circuitry for partial power-down mode operation and provides high-speed performance suitable for direct interface with TTL levels.

Latches Feature Summary

• Features overvoltage tolerant inputs allowing safe interfacing with systems operating at higher voltages than the supply rail.
• Includes I_OFF circuitry that disables outputs during partial power-down to prevent damaging backflow current.
• Provides 3-state non-inverting outputs controlled by a common output enable input for efficient bus-oriented applications.

Latches Applications

• Bus-oriented data storage in microprocessor systems
• Interface between microprocessors and peripheral devices
• Octal data latching in communication equipment

Latches Procurement Notes

Verify component authenticity through authorized Nexperia distributors or certified partners. Confirm the specific ordering suffix matches the required package variant. Check current lifecycle status as availability may vary. Ensure compliance with RoHS directives relevant to your region. Validate pinout compatibility with existing PCB layouts before finalizing procurement decisions.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with 3-state bus capabilities. It is suitable for applications needing direct interface with TTL logic levels while operating on 3.3 V supplies. Consider its overvoltage tolerance for mixed-voltage environments. Evaluate the TSSOP-20 package constraints against available board space requirements.

Latches Part Context
