SN74LV573APW

Latches Overview

The SN74LV573APW is an octal transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports propagation delays of 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. The device draws a maximum static current of 20 uA and provides low-level output currents of 32 mA with high-level output currents of -16 mA. It functions reliably across an operating temperature range from -40 C to +85 C and is housed in a 20-pin SOIC package.

Latches Feature Summary

• Octal configuration providing eight independent data latching channels
• Three-state outputs enabling direct bus-driven connections
• Wide supply voltage compatibility supporting 2 V to 5.5 V operation

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory mapping systems
• Clock domain crossing synchronization buffers

Latches Procurement Notes

Verify the specific suffix 'PW' corresponds to the SOIC-20 tube packaging format rather than tape-and-reel configurations. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified -40 C to +85 C operational envelope for reliable performance.

Latches Selection Notes

Select this component when designing systems requiring wide voltage tolerance between 2 V and 5.5 V. The SOIC-20 package offers surface-mount convenience for space-constrained layouts. Consider the 32 mA drive capability for moderate load requirements without external buffering.

Latches Part Context

This part belongs to the SN74LV573A logic family of octal D-type latches. It shares functional similarities with other variants like SN74LV573ADBR but differs in physical packaging. The LV series emphasizes low power consumption while maintaining speed suitable for general-purpose digital logic applications.

Latches Replacement Considerations

SN74LV573ADBR serves as a pin-compatible alternative in SSOP-20 packaging. SN74LV573APWR offers identical electrical characteristics in tape-and-reel format.
