74LVC373APW,112

Latches Overview

The Nexperia 74LVC373APW,112 is an octal D-type transparent latch with 3-state outputs housed in a TSSOP20 package (SOT360-1). It operates on 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 tolerance, and IOFF circuitry for partial power-down protection. Propagation delays range from 1.5 ns to 9.0 ns depending on voltage.

Latches Feature Summary

• Provides 5 V tolerant inputs and outputs compatible with mixed 3.3 V and 5 V 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 Procurement Notes

Verify the specific ordering suffix ',112' corresponds to the TSSOP20 (SOT360-1) package variant as defined in the official Nexperia documentation. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided for this part number. Ensure design compatibility with the specified JEDEC standards for the intended supply voltage levels.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for low-voltage CMOS applications. It is suitable for designs needing direct interface with TTL levels and high noise immunity. Consider the TSSOP20 package constraints and the wide supply voltage flexibility ranging from 1.2 V to 3.6 V for system integration.

Latches Part Context

This device belongs to the 74LVC373A family of octal D-type transparent latches. Other available packages for this logic function include SO20 (SOT163-1) and DHVQFN20 (SOT764-1), offering alternative form factors while maintaining identical electrical characteristics and functionality across the series.

Latches Replacement Considerations

Direct substitutes within the same package include other manufacturers' 74LVC373 variants. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
