SN74LVTH573PWR

Latches Overview

The SN74LVTH573PWR is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It belongs to the LVTH logic series and operates within a supply voltage range of 2.7 V to 3.6 V. The device features eight circuits in a TSSOP-20 package, providing non-inverting logic functionality. 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. Static current is specified at 5 mA. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides octal data storage with transparent latching behavior for direct input-to-output transmission when enabled.
• Features 3-state outputs to facilitate bus-oriented architectures and system interconnects.
• Operates on a single 3.3-V power supply using ABT technology for optimized performance.

Latches Applications

• Bus-oriented memory mapping
• Clock drivers
• Buffer registers

Latches Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration required for automated assembly processes. Ensure the selected variant matches the intended volume needs and that the component meets RoHS compliance standards for the target market. Cross-reference the manufacturer part number with official distributor catalogs to confirm authenticity and traceability before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring 3.3-V logic levels with high-speed data latching capabilities. The LVTH series offers a balance of speed and power consumption suitable for portable applications. Consider the TSSOP-20 package dimensions for PCB layout constraints and verify that the 32 mA drive capability meets the load requirements of the connected circuitry without exceeding thermal limits.

Latches Part Context

This device is part of the SN74LVTH573 family of octal transparent D-type latches. It shares functional similarities with other members like the SN74LVTH573DBR but differs in physical packaging. The LVTH series utilizes Advanced BiCMOS Technology (ABT) to achieve high-speed operation while maintaining low power dissipation, distinguishing it from standard TTL or older CMOS logic families in modern digital designs.

Latches Replacement Considerations

The SN74LVTH573DBR serves as a verified substitute offering identical logical functionality in an SSOP-20 package. Designers must account for pin-compatible mechanical differences when swapping between TSSOP and SSOP footprints during board revisions or supply chain adjustments.
