74ALVC04PW,112

Overview

The Nexperia 74ALVC04PW,112 is a hex inverter housed in a TSSOP14 (SOT402-1) package. 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 tolerance to slow signal transitions and includes IOFF circuitry to prevent backflow current during partial power-down states. Static characteristics include input leakage currents up to ±20 μA at maximum ratings and typical propagation delays ranging from 1.0 ns to 3.8 ns depending on voltage and temperature conditions.

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry disables outputs to prevent potentially damaging backflow current when the device is powered down.
• Overvoltage tolerant inputs allow direct interfacing with TTL levels without external components.

Applications

• Partial power-down applications requiring protection against backflow current
• Signal inversion in mixed-voltage logic environments
• Clock distribution circuits requiring noise immunity

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 tape-and-reel packaging configuration as defined in the official Nexperia data sheet. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits for your application environment. Ensure design compliance with the absolute maximum ratings to avoid permanent damage.

Selection Notes

Select this component when a hex inverter with Schmitt-trigger inputs is required for noisy or slow-signal environments. The TSSOP14 package offers a compact solution for space-constrained designs. Consider the IOFF feature if the system utilizes partial power-down modes to protect downstream components from reverse current flow.

Part Context

This part belongs to the 74ALVC family of high-speed CMOS logic devices manufactured by Nexperia. The ALVC series is designed for low voltage operation while maintaining performance suitable for modern digital systems. The 74ALVC04 specifically provides six independent inverters in a single package, serving as a fundamental building block for digital logic circuits.

Replacement Considerations

The 74ALVC04D,112 serves as a functional substitute using an SO14 package instead of TSSOP14. Designers must account for differences in physical dimensions and thermal dissipation characteristics between the SOT402-1 and SOT108-1 packages when swapping these variants.

FAQ

How does the IOFF circuitry function in this device?

The IOFF circuitry automatically disables the outputs when the supply voltage (VCC) is zero. This prevents potentially damaging backflow current from flowing through the device when it is powered down but connected to active circuits.

What is the purpose of the Schmitt-trigger inputs?

The Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This improves noise immunity and ensures clean switching even with degraded signal edges.
