74ALVC08PW,118

Overview

The Nexperia 74ALVC08PW,118 is a quad 2-input AND gate in the ALVC logic series. 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 utilizes Schmitt-trigger inputs for noise tolerance and includes IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 3.7 ns depending on voltage and temperature. It is housed in a TSSOP14 (SOT402-1) package with 14 leads.

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry disables outputs during partial power-down to prevent damaging 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 backflow current prevention
• Mixed voltage systems interfacing 3.3 V or 5 V devices
• Digital logic circuits requiring noise immunity via Schmitt triggers

Selection Notes

Select this component when low power dissipation and high-speed operation are required alongside robust ESD protection. The ALVC series offers faster switching than standard LVC variants while maintaining compatibility with 3.3 V and 5 V systems. Ensure the design accounts for the specified propagation delays and power dissipation capacitance values under the intended load conditions.

Part Context

This part belongs to the Nexperia 74ALVC family of advanced low-voltage CMOS logic gates. The 74ALVC08 specifically implements four independent 2-input AND functions. It is designed for high-speed digital applications where low power consumption and wide operating voltage ranges are critical constraints.

Replacement Considerations

Direct pin-compatible alternatives include the 74ALVC08D (SO14 package) and 74ALVC08BQ (DHVQFN14 package). Verify that the substitute package type meets the mechanical footprint requirements of the target PCB design.

FAQ

How does the IOFF feature function?

The IOFF circuitry automatically disables the outputs when the device is powered down (VCC = 0 V), preventing potentially damaging backflow current through the device.

What is the input voltage tolerance?

The inputs are overvoltage tolerant up to 3.6 V, allowing them to interface directly with TTL levels even when the supply voltage is lower.
