SN74AC573DBR

Latches Overview

The SN74AC573DBR is an octal transparent D-type latch manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2V to 6V and utilizes a 20-pin SOIC surface-mount package. The device provides non-inverting logic with eight independent circuits. Key electrical characteristics include a propagation delay of 2.5ns and output drive capabilities of 24mA for both high and low states. It functions reliably across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with eight independent data paths
• Three-state outputs enabling direct bus-driven connections without external buffers
• Wide operating voltage compatibility ranging from 2V to 6V
• High-speed performance with 2.5ns propagation delay

Latches Applications

• Registering fast-acting microprocessor data
• Performing temporary storage in buffered memory systems
• Driving bus-oriented architectures requiring tri-state control

Latches Procurement Notes

Verify the specific package variant against design requirements, as the DBR suffix indicates a tape-and-reel configuration suitable for automated assembly. Confirm that the 20-SOIC footprint matches the PCB layout. Ensure the selected component meets the required voltage and current specifications for the target application environment before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring high-density octal latching with three-state output control. It is suitable for applications needing wide voltage tolerance between 2V and 6V. Consider the 2.5ns speed for high-frequency data handling. Compare against other series like LVTH or HC if lower power consumption or different voltage levels are prioritized over speed.

Latches Part Context

This part belongs to the SN74AC573 family of octal D-type latches with three-state outputs. It shares functional similarities with other variants such as SN74AC573DWR and SN74AC573DWRE4, differing primarily in packaging and manufacturing revisions. The AC series offers faster switching speeds compared to standard HC or HCT logic families while maintaining compatible pinouts.

Latches Replacement Considerations

SN74AC573DWR serves as a direct alternative with identical functionality but may differ in reel specifications. SN74AC573DWRE4 represents a lead-free revision of the same device. Verify pinout compatibility and electrical parameters before substituting.
