SN74LVTH573DW

Overview

The SN74LVTH573DW 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 circuits housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports surface-mount installation. Key electrical parameters include a propagation delay of 2.9 ns at 3.3 V, a maximum static current of 5 mA, and output drive capabilities of 32 mA for both low and high states. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides octal latching functionality with true logic type for data storage applications
• Features three-state outputs enabling direct bus-driven connections
• Operates within a specific 2.7 V to 3.6 V supply voltage window

Applications

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

Procurement Notes

Verify the exact ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental files. Ensure the selected variant matches the required lead-free manufacturing standards for your assembly process.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 2.7 V and 3.6 V with moderate speed requirements. The LVTH series offers a balance of performance and power consumption suitable for portable electronics. Consider the SOIC-20 package dimensions for PCB layout constraints and thermal management needs during integration.

Part Context

This part belongs to the SN74LVTH573 family of octal D-type latches. It serves as a successor to older logic families, offering improved switching speeds while maintaining compatibility with standard digital interfaces. The device is designed for general-purpose logic applications requiring reliable data retention and bus driving capabilities.

Replacement Considerations

SN74LVTH573DWR is available as a reel-packaged alternative from the same manufacturer.
