Nexperia USA Inc. 74AUP1G19GW,125

Overview

74AUP1G19GW,125 from Nexperia is a low-power 1-of-2 decoder/demultiplexer with common active-low enable (E), true (1Y) and complement (2Y) outputs, Schmitt-trigger inputs, IOFF partial power-down support, and operation across 0.8 V to 3.6 V supply. It buffers input A to both outputs when E is LOW and forces both outputs HIGH when E is HIGH-used in voltage-level translation, signal routing, and power-gated logic control in portable and battery-powered systems.

For engineers reviewing the 74AUP1G19GW,125 datasheet, 74AUP1G19GW,125 pinout, 74AUP1G19GW,125 application, or 74AUP1G19GW,125 equivalent, key selection criteria include its ultra-low ICC (≤0.9 µA max), wide VCC range (0.8–3.6 V), IOFF-enabled safe power-down behavior, and TSSOP6 package compatibility with high-density PCB layouts.

Technical Context

This device implements a single-bit address decode function with dual complementary outputs, where input A determines output polarity while enable E controls output state globally. Its Schmitt-trigger inputs tolerate slow-rising/falling signals up to 200 ns/V transition rate, enabling robust interfacing with noisy or RC-filtered sources.

The IOFF circuit disables outputs when VCC = 0 V, limiting backflow current to ±0.75 µA max and supporting hot-insertion and partial system power-down. All static and dynamic parameters-including VIH/VIL thresholds, VOH/VOL levels, and tpd propagation delay-are fully characterized from –40 °C to +125 °C across the full 0.8–3.6 V VCC range.

FAQ

Does 74AUP1G19GW,125 support hot insertion?

Yes. The IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 µA maximum even with input/output voltages up to 3.6 V. This enables safe insertion into live backplanes or partially powered systems without risk of latch-up or damage.

Can 74AUP1G19GW,125 operate at 0.8 V with full timing performance?

Yes. Propagation delay is specified down to 0.8 V (e.g., 15.9 ns typical A→1Y at CL = 5 pF), and all DC parameters-including VIH/VIL thresholds and VOH/VOL levels-are guaranteed across the full 0.8–3.6 V range per Table 7 and Table 8 of the Rev. 8 datasheet.

What is the significance of Schmitt-trigger inputs in this device?

Schmitt-trigger inputs provide hysteresis (≥0.3 × VCC), allowing reliable recognition of slow-rising or noisy signals-such as those from mechanical switches, RC networks, or long PCB traces-without external debouncing components. This reduces BOM count and improves system-level noise immunity.

Is 74AUP1G19GW,125 pin-compatible with other 74AUP1Gxx variants in TSSOP6?

No. While it shares the SOT363-2 footprint, pin assignments differ across the 74AUP1Gxx family (e.g., 74AUP1G00 uses different I/O mapping). Always verify pin configuration against Figure 2 in the datasheet-this device has fixed pinout: A(1), GND(2), E(3), 2Y(4), VCC(5), 1Y(6).
