SN74LVTH373DW

Latches Overview

The SN74LVTH373DW is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LVTH logic series. It features non-inverting outputs and operates within a supply voltage range of 2.7 V to 3.6 V. The device provides high-speed performance with a propagation delay of 2.6 ns at 3.3 V. It supports low-level output currents of 32 mA and high-level output currents of -32 mA. Designed for surface-mount applications, it utilizes a SOIC-20 package and functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with eight independent data channels
• High-speed operation enabled by advanced BiCMOS technology
• Bus-holding inputs eliminate the need for external pull-up resistors on unused lines
• Designed for 3.3V ABT systems while providing TTL-compatible interfaces in 5V environments

Latches Applications

• Bus structure system applications requiring data latching
• Low-voltage (3.3V) memory address and data latching
• Interface circuits between 3.3V devices and 5V TTL environments
• Parallel-to-serial conversion modules in digital communication systems

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and RoHS compliance status. Confirm that the SOIC-20 package dimensions match your PCB footprint requirements. Check for any recent product change notifications regarding material composition or manufacturing site changes before finalizing procurement plans.

Latches Selection Notes

Select this component when designing systems requiring fast switching speeds combined with low power consumption typical of CMOS technologies. Ensure the design accommodates the specified 2.7V to 3.6V supply voltage range. Consider the bus-holding feature if minimizing external components on unused input pins is a priority for the circuit layout.

Latches Part Context

This part belongs to the SN74LVTH373 family of octal latches. It shares functional similarities with other members like the SN74LVTH373PWR but differs in physical packaging. The DW suffix specifically denotes the SOIC-20 surface-mount package, distinguishing it from TSSOP or tube-packaged variants within the same logical family.

Latches Replacement Considerations

SN74LVTH373PWRE4 offers identical electrical characteristics in a TSSOP-20 package.
