74LVC373ADB,112

Latches Overview

The Nexperia 74LVC373ADB,112 is an octal D-type transparent latch with 3-state outputs housed in a SO20 plastic small outline package (SOT163-1). It operates within a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes latch enable (LE) and output enable (OE) controls, Schmitt-trigger inputs for noise immunity, and IOFF circuitry for partial power-down applications.

Latches Feature Summary

• Provides 5 V tolerant inputs and outputs suitable for mixed voltage environments
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down
• Features Schmitt-trigger action at all inputs to tolerate slower rise and fall times

Latches Applications

• Translators in mixed 3.3 V and 5 V environments
• Partial power down applications requiring backflow current prevention
• Bus-oriented applications utilizing 3-state non-inverting outputs

Latches Selection Notes

Select this component when designing systems requiring octal latching with 3-state bus capabilities. Ensure the application utilizes supply voltages between 1.2 V and 3.6 V. Consider the SO20 package dimensions if space constraints exist. Verify that input signals do not exceed the 5.5 V tolerance limit under any operating condition.

Latches Part Context

This part belongs to the 74LVC373A family of octal D-type transparent latches. It shares functional characteristics with other variants like the 74LVC373APW and 74LVC373ABQ, differing primarily in packaging. The AD variant specifically denotes the SO20 plastic small outline package configuration.

Latches Replacement Considerations

The 74LVC373AD is the base type number for this package variant. Other packages in the same logical family include 74LVC373APW (TSSOP20) and 74LVC373ABQ (DHVQFN20). Direct pin-compatible substitution requires matching the package type.
