74LV373PW,112

Latches Overview

The NXP USA Inc. 74LV373PW,112 is an octal D-type transparent latch featuring 3-State outputs in a 20-pin TSSOP package. It operates within a supply voltage range of 1.0V to 5.5V and supports temperatures from -40°C to +125°C. Key electrical parameters include a typical propagation delay of 10ns at 3.3V (Dn to Qn) and 12ns (LE to Qn). The device accepts TTL input levels between VCC = 2.7V and 3.6V, with a typical output ground bounce of 2V at 3.3V.

Latches Feature Summary

• Octal D-type transparent latch architecture with separate data inputs for each latch
• Common 3-State output enable input suitable for bus-oriented applications
• Optimized for low-voltage operation with wide operating voltage range
• Functionally identical to the 74LV573 but with a different pin arrangement

Latches Applications

• Bus driver applications requiring 3-State outputs
• Low-voltage logic systems operating between 1.0V and 5.5V
• Digital data storage and transfer in transparent latch mode

Latches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specified in official documentation. Check for obsolescence notices, as this part may be discontinued. Ensure packaging matches the TSSOP-20 specification required for your design.

Latches Selection Notes

Select this component when an octal latch with 3-State outputs is required in a compact TSSOP-20 form factor. It is functionally compatible with 74HC/HCT373 devices. Consider the 1.0V to 5.5V operating range for low-power designs. Verify that the 10ns propagation delay meets system timing requirements at the target supply voltage.

Latches Part Context

The 74LV373 belongs to the LV (Low-Voltage CMOS) logic family, designed for applications requiring lower power consumption and wider voltage flexibility compared to standard HC series. It serves as a memory element in digital circuits, capturing data on the rising edge of the latch enable signal while providing high-impedance states for bus sharing.

Latches Replacement Considerations

The datasheet notes functional identity with the 74LV573, though pin arrangements differ. No other specific substitute part numbers are confirmed in the provided source material.
