74LVC373ADB,118

Latches Overview

The NXP USA Inc. 74LVC373ADB,118 is an octal D-type transparent latch with 3-state outputs housed in a SO20 plastic small outline package (SOT163-1). It features latch enable and output enable inputs for data storage and high-impedance control. The device supports a wide supply voltage range from 1.2 V to 3.6 V and includes overvoltage tolerant inputs up to 5.5 V. Propagation delays range from 1.5 ns to 9.0 ns depending on voltage. It operates from -40 °C to +125 °C and complies with JEDEC standards.

Latches Feature Summary

• Features Schmitt-trigger action at all inputs to tolerate slower input rise and fall times.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down applications.
• Provides high-impedance outputs when the supply voltage is zero volts.

Latches Applications

• Mixed 3.3 V and 5 V environments requiring level translation
• Partial power-down mode operation using IOFF circuitry
• Octal bus driver applications

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the temperature range specification aligns with system requirements. Ensure the manufacturer designation corresponds to the intended source, noting potential transitions between NXP and Nexperia branding for this component line.

Latches Selection Notes

Select this component for designs requiring octal latching with 3-state capability and low-voltage operation. The wide supply range accommodates various logic families. Verify input voltage tolerance if interfacing with 5 V signals directly. Consider the thermal dissipation limits for the SO20 package under maximum load conditions.

Latches Part Context

This component belongs to the 74LVC373A family of octal D-type transparent latches. The 'ADB' suffix specifically denotes the SO20 package variant. The product line has transitioned from NXP Semiconductors to Nexperia B.V., which now manufactures and distributes these devices under updated datasheet revisions.

Latches Replacement Considerations

The 74LVC373APW is a compatible alternative within the same family but utilizes a TSSOP20 package instead of the SO20 form factor. Verify pinout compatibility and physical dimensions before substituting.
