Nexperia USA Inc. 74ALVC14PW,118

Overview

74ALVC14PW,118 from Nexperia is a hex inverting Schmitt trigger IC operating from 1.65 V to 3.6 V supply, featuring IOFF partial power-down protection, ±50 mA output drive, and -40 °C to +125 °C temperature rating. It provides noise-immune signal conditioning for digital interface circuits in industrial control and sensor signal conditioning applications.

For engineers reviewing the 74ALVC14PW,118 datasheet, 74ALVC14PW,118 pinout, 74ALVC14PW,118 application, or 74ALVC14PW,118 equivalent, key selection factors include Schmitt-trigger hysteresis (0.3 V to 1.2 V), propagation delay down to 1.0 ns at 3.0 V, IOFF leakage < ±10 μA at VCC = 0 V, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

This device implements six independent CMOS inverters, each with Schmitt-trigger inputs providing hysteresis to reject input noise and ensure clean transitions on slow or noisy signals. The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C/JESD36 (2.7–3.6 V), and supports direct TTL-level interfacing while maintaining overvoltage tolerance up to 3.6 V on inputs regardless of VCC level.

FAQ

What is the minimum supply voltage required for guaranteed operation?

The 74ALVC14PW,118 is fully specified from 1.65 V to 3.6 V per JEDEC JESD8-7. At 1.65 V, VIH is guaranteed ≥1.25 V and VOL ≤0.3 V with 6 mA load, enabling interoperability with 1.8 V logic families. Operation below 1.65 V is not characterized and may result in undefined output states or increased propagation delay.

How does the IOFF feature behave during power sequencing?

When VCC drops to 0 V, the IOFF circuit automatically disables all six outputs, limiting leakage current to ±10 μA maximum. This prevents backflow current from powered downstream logic into the unpowered IC, protecting both devices during hot-swap or staggered power-up sequences in modular systems.

Can this device drive a 50 pF capacitive load at 3.3 V with sub-4 ns delay?

Yes. At VCC = 3.3 V and CL = 50 pF, typical propagation delay is 2.4 ns with max 3.4 ns (–40 °C to +125 °C), meeting sub-4 ns requirement. Rise/fall times remain ≤2.5 ns under these conditions, verified per JEDEC test circuit Fig. 5 with RL = 500 Ω and VEXT = 2.7 V.

Is the TSSOP14 package RoHS-compliant and lead-free?

Yes. The SOT402-1 package used for 74ALVC14PW,118 is lead-free and RoHS-compliant per Nexperia's product compliance documentation. Terminal finish is matte tin, and the package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/60% RH.
