74ALVC14PW,112

Overview

The Nexperia 74ALVC14PW,112 is a hex inverting Schmitt trigger manufactured by Nexperia B.V. It operates within a supply voltage range of 1.65 V to 3.6 V and features CMOS low power dissipation. The device includes IOFF circuitry for partial power-down applications, preventing backflow current when powered down. It provides overvoltage tolerant inputs up to 3.6 V and direct interface with TTL levels. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is specified from -40 °C to +125 °C and complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36.

Feature Summary

• Hex inverting buffers with Schmitt-trigger action for signal conditioning
• IOFF circuitry enables safe partial power-down mode operation
• Overvoltage tolerant inputs compatible with 3.6 V systems
• High ESD protection performance exceeding industry standards

Applications

• Signal conditioning for slowly changing input signals
• Partial power-down system designs requiring backflow prevention
• Interfaces between different logic families with varying voltage levels

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 package (SOT402-1) as defined in the official Nexperia data sheet. Confirm that the procurement channel sources directly from authorized distributors or Nexperia to ensure authenticity. Check for any recent product change notices regarding the SOT402-1 package outline alignment with JEDEC MO-153 standards.

Selection Notes

Select this component when hex inversion with hysteresis is required in low-voltage CMOS environments. Ensure the application demands input tolerance up to 3.6 V regardless of the supply voltage. Verify that the thermal management requirements align with the TSSOP14 package derating characteristics above 81 °C. Consider the IOFF feature if the design involves hot-swap or partial power scenarios.

Part Context

This part belongs to the 74ALVC14 family of high-performance, low-power, low-voltage Si-gate CMOS devices. It is designed to be superior to most advanced CMOS compatible TTL families. The PW suffix indicates the plastic thin shrink small outline package with 14 leads. It serves as a digital logic buffer/inverter within the broader ALVC logic series.

Replacement Considerations

Direct substitutes include other 74ALVC14 variants such as 74ALVC14D (SO14 package) or 74ALVC14BQ (DHVQFN14 package), provided the pinout and electrical specifications remain identical. Cross-reference with equivalent parts from other manufacturers like Texas Instruments, ensuring functional compatibility and package dimensions match.
