74ALVC08D,118

Overview

The Nexperia 74ALVC08D,118 is a quad 2-input AND gate in the ALVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 3.7 ns depending on voltage and temperature. Static characteristics include low leakage currents and high ESD protection ratings exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interface with TTL levels up to 3.6 V.
• Latch-up performance exceeds 250 mA per JESD78 Class II.A standards.

Applications

• Partial power-down applications requiring output isolation during power-off states.
• Digital signal processing circuits utilizing CMOS low power dissipation.
• Mixed-voltage systems interfacing between different logic families.

Selection Notes

Select this component when designing systems requiring robust noise immunity via Schmitt triggers or operation across wide voltage swings from 1.65 V to 3.6 V. The SO14 package is suitable for surface-mount assembly where thermal management and lead pitch compatibility are required. Ensure application constraints align with the specified -40 °C to +125 °C operating temperature range.

Part Context

This part belongs to the Nexperia 74ALVC series of advanced low-voltage CMOS logic gates. The 'D' suffix indicates the SO14 plastic small outline package variant. It is functionally equivalent to other 74ALVC08 devices but distinguished by its specific physical footprint and pin configuration defined by the SOT108-1 standard.

Replacement Considerations

Compatible alternatives include the 74ALVC08PW (TSSOP14 package) and 74ALVC08BQ (DHVQFN14 package) from Nexperia, which share identical electrical specifications but differ in physical dimensions and mounting style.

FAQ

How does the IOFF circuitry function in this device?

The IOFF circuitry disables the outputs when the device is powered down (VCC = 0 V), preventing potentially damaging backflow current through the device if input or output pins are held at 3.6 V.

What is the purpose of the Schmitt-trigger inputs?

The Schmitt-trigger action makes the circuit tolerant for slower input rise and fall times, improving noise immunity compared to standard logic gates without hysteresis.
