SN74LVTH373PWR

Overview

The SN74LVTH373PWR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LVTH logic series. It features a single circuit with eight output lines housed in a TSSOP-20 package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports a minimum operating temperature of -40°C and a maximum of +85°C. Key electrical parameters include a propagation delay of 2.6 ns at 3.3 V, a static current of 5 mA, and output drive capabilities of 32 mA for both low and high states.

Feature Summary

• Transparent data latching functionality controlled by a dedicated latch enable signal
• Bus-holding inputs eliminate the need for external pull-up resistors on unused lines
• High-drive outputs support system hot insertion without causing bus interference
• Compatible with 5V TTL interfaces while operating at lower 3.3V logic levels

Applications

• Bus structure systems requiring address or data storage
• Portable equipment utilizing low-voltage power supplies
• Consumer electronics demanding high-speed CMOS performance
• Industrial control systems with mixed voltage environments

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS requirements if applicable to your manufacturing standards. Cross-reference the datasheet revision date to confirm compatibility with your design constraints. Confirm that the TSSOP-20 footprint matches your PCB layout guidelines before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require octal data storage with high drive strength and low power consumption. The LVTH series offers speed comparable to 5V ABT technology while maintaining CMOS efficiency. Consider the 2.6 ns propagation delay for timing-critical applications. Verify that the 3.3V operating range aligns with your system's power distribution network and I/O voltage levels.

Part Context

This part belongs to the SN74LVTH373 family of octal transparent latches. It utilizes advanced BiCMOS technology to achieve high-speed operation similar to older 5V standards. The device provides non-inverting outputs and is designed for use in bus-oriented architectures where data transparency and latching are required.

Replacement Considerations

The SN74LVTH373PWRE4 is a verified equivalent variant from the same manufacturer. Check pinout compatibility and electrical specifications before substituting.
