SN74LVTH573DWR

Overview

The SN74LVTH573DWR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LVTH logic series. It features a non-inverting configuration with eight independent D-type latches and three-state outputs. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a propagation delay of 2.9 ns at 3.3 V, low-level output current of 32 mA, and high-level output current of -32 mA. It is housed in a 20-SOIC package and supports surface-mount installation.

Feature Summary

• Provides octal data storage via eight independent transparent D-type latches for parallel data handling.
• Features three-state outputs that allow direct connection to bus-oriented systems without additional interface hardware.
• Operates on a single 3.3-V power supply, enabling compatibility with standard low-voltage digital environments.

Applications

• Bus-oriented memory mapping
• Register banks
• Clock buffers

Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS standards and matches the intended voltage domain of 2.7 V to 3.6 V. Ensure the SOIC-20 footprint aligns with the design layout before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring 3.3-V operation with high-speed data latching capabilities. The LVTH series offers a balance of speed and power consumption suitable for portable applications. Consider the three-state output feature if the design requires shared bus architectures or direct interfacing with microprocessors.
