Nexperia USA Inc. 74ALVC02PW,112

Overview

74ALVC02PW,112 from Nexperia is a quad 2-input NOR gate logic IC with Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operation across 1.65 V to 3.6 V supply. It delivers propagation delays as low as 1.0 ns (typical at VCC = 3.3 V), supports −40 °C to +125 °C ambient range, and features overvoltage-tolerant inputs up to 3.6 V - used in industrial control signal conditioning and level-shifting interfaces.

For engineers reviewing the 74ALVC02PW,112 datasheet, 74ALVC02PW,112 pinout, 74ALVC02PW,112 application, or 74ALVC02PW,112 equivalent, key selection criteria include IOFF-enabled bus isolation during power sequencing, Schmitt-trigger input hysteresis for slow-edge signal cleanup, guaranteed 125 °C operation, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

This device implements four independent 2-input NOR gates in a single monolithic CMOS structure, each with Schmitt-trigger input thresholds enabling robust operation with slow-rising or noisy digital signals. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and supporting hot-swap and partial-power-down system architectures.

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 meets HBM ESD >2000 V and CDM >1000 V per JS-001/JS-002. Input voltage tolerance extends to 3.6 V regardless of VCC, enabling direct interfacing with 3.3 V and 2.5 V logic families.

FAQ

Does the 74ALVC02PW,112 support hot-swap insertion while system power is active?

Yes - its IOFF circuitry disables outputs when VCC = 0 V, preventing back-current flow during live insertion. This feature is validated per JESD78 Class II.A latch-up testing and supports hot-swap compliance in modular power systems and PCIe add-in cards where rail sequencing is asynchronous.

Can the 74ALVC02PW,112 safely interface a 5 V TTL output without external components?

No - while inputs tolerate up to 3.6 V, a 5 V TTL signal exceeds the absolute maximum input voltage rating of +4.6 V only under clamped current conditions. Direct connection risks damage; a series resistor + internal clamp or dedicated level shifter is required for sustained 5 V interface.

What is the minimum recommended load capacitance for achieving specified propagation delay?

The datasheet specifies tpd test conditions with 30 pF (for VCC ≤ 2.7 V) or 50 pF (for VCC ≥ 3.0 V) total load, including probe and PCB trace capacitance. Operating below these values may reduce delay slightly but is not characterized; design margins should assume the published max tpd at rated CL.

Is the exposed pad on the TSSOP14 package (SOT402-1) electrically connected?

No - the exposed pad in SOT402-1 is a thermal enhancement feature with no electrical function. Nexperia documentation states it has no electrical or mechanical requirement to be soldered; if connected, it must remain floating or tied to GND to avoid unintended coupling or thermal stress.
