SN74LV573ATPWR

Latches Overview

The SN74LV573ATPWR is an octal transparent D-type latch manufactured by Texas Instruments. It features eight non-inverting outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a propagation delay of 9.5 ns at 5 V and maintains a static current of 2 uA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -16 mA. It is housed in a TSSOP-20 package and supports surface mount installation with an operating temperature range from -40 C to +85 C.

Latches Feature Summary

• Octal configuration providing eight independent data latching channels
• Non-inverting logic polarity for direct signal transmission
• Low quiescent current consumption for power efficiency
• High-drive output capability suitable for bus-oriented systems

Latches Applications

• Bus-oriented architectures requiring data storage
• Clocked digital I/O port implementations
• Register applications in computing systems

Latches Procurement Notes

Verify the specific suffix 'TPWR' corresponds to the TSSOP-20 package and reel packaging format as listed in official Texas Instruments documentation. Confirm RoHS compliance status through the manufacturer's current product information page. Ensure the ordering part number matches the exact electrical specifications required for your design, particularly the 4.5 V to 5.5 V supply voltage constraint.

Latches Selection Notes

Select this component when designing 5 V logic systems requiring octal latching functionality. The SN74LV573ATPWR is appropriate for applications needing moderate speed performance with a 9.5 ns propagation delay. Consider the TSSOP-20 package dimensions for PCB layout constraints. Verify that the system operates strictly within the specified 4.5 V to 5.5 V voltage range to ensure reliable operation.

Latches Part Context

This device belongs to the SN74LV573A series of octal transparent D-type latches. It shares functional similarities with other members of the LV logic family but is distinguished by its specific package type and voltage operating range. The component serves as a standard solution for data retention in synchronous digital circuits.

Latches Replacement Considerations

The SN74LV573ADBR offers identical electrical characteristics but utilizes an SSOP-20 package instead of TSSOP-20. Designers must verify pin-to-pin compatibility and physical footprint differences before substituting.
