Nexperia USA Inc. 74AUP1G3208GXZ

Overview

74AUP1G3208GXZ from Nexperia is a single low-power 3-input OR-AND logic gate (Y = (A + B) × C) with Schmitt-trigger inputs, operating from 0.8 V to 3.6 V supply, delivering 0.9 μA max ICC at 25 °C, -40 °C to +125 °C temperature range, and 3.2 ns propagation delay at 3.0 V/5 pF load. It serves as a compact combinational logic element in battery-powered sensor interfaces and I/O signal conditioning circuits.

For engineers reviewing the 74AUP1G3208GXZ datasheet, 74AUP1G3208GXZ pinout, 74AUP1G3208GXZ application, or 74AUP1G3208GXZ equivalent, key selection criteria include its IOFF-enabled partial power-down capability, overvoltage-tolerant 3.6 V inputs, sub-1 μA static current, Schmitt-trigger noise immunity, and X2SON6 (SOT1255-2) 1.0 × 0.8 × 0.32 mm package for space-constrained PCB layouts.

Technical Context

This device implements a fixed Boolean function Y = (A + B) × C - not configurable - with all three inputs featuring Schmitt-trigger thresholds for robust noise rejection on slow-rising signals. Its IOFF circuit actively disables outputs during VCC = 0 V, preventing backflow current in partial power-down systems.

It complies with JEDEC standards JESD8-12 through JESD8C across five voltage bands and supports dynamic operation up to 100 MHz (at VCC ≥ 2.3 V, CL = 5 pF), with CPD = 4.0 pF enabling precise dynamic power estimation via PD = CPD × VCC² × fi × N.

FAQ

Does 74AUP1G3208GXZ support true 0 V to 3.6 V input tolerance independent of VCC?

Yes - all inputs (A, B, C) are overvoltage tolerant to 3.6 V regardless of VCC level, including VCC = 0 V. This allows safe interfacing with higher-voltage peripherals even during power sequencing or partial shutdown, without external clamping diodes or level shifters.

What is the functional difference between Y = (A + B) × C and a standard 3-input AND or OR gate?

Unlike a 3-input AND (Y = A × B × C) or OR (Y = A + B + C), this gate implements a hierarchical function: the OR of inputs A and B is first computed, then logically ANDed with input C. This enables conditional gating - e.g., "activate if fault-A OR fault-B occurs AND system is enabled" - in a single device.

How does the IOFF feature behave when VCC is ramping or floating?

IOFF activates when VCC falls below ~0.2 V and remains active until VCC rises above ~0.4 V. During this transition window, output Y is actively driven to high-impedance state, preventing back-current even if inputs A/B/C are held at valid logic levels - critical for hot-swap and multi-rail systems.

Can the Schmitt-trigger inputs be bypassed or disabled for standard CMOS threshold operation?

No - Schmitt-trigger action is inherent to the input structure and cannot be disabled. The hysteresis (typically 0.3×VCC) is fixed and provides guaranteed noise margin; it is not a selectable feature but a core design characteristic enabling reliable operation on slow or noisy signals.
