74LV373DB,112

Latches Overview

The NXP USA Inc. 74LV373DB,112 is an octal D-type transparent latch with 3-State outputs housed in a 20-pin SSOP package. It operates within a supply voltage range of 1.0V to 5.5V and supports temperatures from -40°C to +125°C. At 3.3V, propagation delays are typically 10ns (Dn to Qn) and 12ns (LE to Qn). The device accepts TTL input levels between VCC = 2.7V and 3.6V, features low output ground bounce, and includes common Latch Enable (LE) and Output Enable (OE) inputs for bus-oriented applications.

Latches Feature Summary

• Octal D-type transparent latch architecture with separate data inputs and 3-State outputs
• Wide operating voltage range supporting low voltage applications down to 1.0V
• Common Latch Enable and Output Enable inputs for simplified bus driver control
• Optimized for low output ground bounce performance

Latches Applications

• Bus-oriented applications requiring transparent latching
• Low voltage logic systems interfacing with 3.3V or 5V domains
• Portable equipment utilizing wide supply voltage flexibility

Latches Procurement Notes

Verify the specific ordering suffix '112' against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through official datasheets as specifications may evolve. Ensure design compatibility with the 20-lead SSOP footprint and thermal derating requirements for the specified operating temperature range.

Latches Selection Notes

Select this component for designs requiring an octal latch with 3-State outputs in a compact surface-mount package. It serves as a pin-compatible alternative to 74HC/HCT373 devices while offering lower voltage operation. Consider the typical propagation delay and power dissipation characteristics when designing for high-speed or low-power constraints within the 1.0V to 5.5V supply range.

Latches Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It is functionally identical to the 74LV573 but utilizes a different pin arrangement. The device is manufactured by Philips Semiconductors, now part of Nexperia/NXP, and represents a standard solution for digital data storage and bus interface tasks in mixed-voltage environments.

Latches Replacement Considerations

The 74LV573 is functionally identical but has a different pin arrangement. Direct pin-for-pin replacements include other manufacturers' 74LV373 variants in SSOP-20 packages, provided they meet the same electrical specifications and package dimensions.
