74ALVC14D,112

Overview

The Nexperia 74ALVC14D,112 is a hex inverting Schmitt trigger manufactured by Nexperia USA Inc. 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 IOFF circuitry for partial power-down applications, preventing backflow current when powered down. Propagation delay ranges from 1.0 ns to 5.1 ns depending on voltage and temperature. Input leakage current is typically ±0.1 μA at 3.6 V, while supply current is typically 0.2 μA. Power dissipation capacitance is typically 25 pF per inverter.

Feature Summary

• Hex inverting Schmitt trigger with six independent channels
• IOFF circuitry enables partial power-down mode operation
• Overvoltage tolerant inputs up to 3.6 V
• Direct interface capability with TTL levels

Applications

• Partial power-down system designs requiring backflow prevention
• Signal conditioning for slow rise and fall times via Schmitt triggers
• Interfacing between different voltage logic nodes

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's official documentation to confirm packaging details and availability status. Confirm that the SO14 package variant matches the required PCB footprint. Ensure compliance with RoHS and REACH regulations as specified in the product data sheet before procurement.

Selection Notes

Select this component when designing circuits requiring noise immunity through Schmitt-trigger action on all inputs. Consider the wide supply voltage range suitable for low-voltage digital systems. Verify thermal derating requirements if operating near the maximum ambient temperature limit of +125 °C.

Part Context

This part belongs to the 74ALVC logic family, which utilizes Advanced Low-Voltage CMOS technology. The 'D' designation indicates the SO14 plastic small outline package with a body width of 3.9 mm. The '112' suffix typically denotes tube packaging, though verification with the datasheet is recommended.

Replacement Considerations

The 74ALVC14PW is a compatible alternative using the TSSOP14 package. The 74ALVC14BQ offers a DHVQFN14 leadless option. Ensure pin compatibility and package dimensions are reviewed when substituting these variants.
