SN74AC573PWR

Latches Overview

The SN74AC573PWR is an octal transparent D-type latch manufactured by Texas Instruments. It features eight D-type latches with three-state outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. Packaged in a 20-pin TSSOP (PowerPAD) surface-mount case, it provides efficient data storage and bus holding capabilities.

Latches Feature Summary

• Octal configuration providing eight independent transparent D-type latches for parallel data handling.
• Three-state outputs enable direct connection to system buses without external drivers.
• Wide supply voltage operation supports compatibility across various logic families.

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus holding registers in microprocessor systems
• High-performance register files

Latches Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP PowerPAD package when sourcing. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure ESD protection protocols are followed during handling due to the CMOS technology used in the AC series.

Latches Selection Notes

Select this component for designs requiring multiple latched outputs with bus isolation. Compare propagation delay specifications against system timing requirements. Consider the thermal performance of the PowerPAD package for heat dissipation needs in dense PCB layouts.

Latches Part Context

This part belongs to the SN74AC573 family of octal latches. It shares functional similarities with other 74AC series devices but offers improved speed over standard 74LS counterparts. The PWR suffix indicates a specific surface-mount package variant optimized for automated assembly.

Latches Replacement Considerations

Check for equivalent parts such as SN74AC573DR or SN74AC573PW depending on required package type. Verify pinout compatibility before substituting with non-Texas Instruments equivalents.
