Nexperia USA Inc. 74AUP1G19GN,132

Overview

74AUP1G19GN,132 from Nexperia is a low-power 1-of-2 decoder/demultiplexer with active-low enable, Schmitt-trigger inputs, IOFF partial power-down support, and operation across 0.8 V to 3.6 V supply. It routes input A to true output 1Y and complement output 2Y when E is LOW; both outputs go HIGH when E is HIGH. Used in battery-powered sensor interfaces and level-shifting I/O expansion in portable industrial controllers.

For engineers reviewing the 74AUP1G19GN,132 datasheet, 74AUP1G19GN,132 pinout, 74AUP1G19GN,132 application, or 74AUP1G19GN,132 equivalent, key selection criteria include ultra-low ICC (≤0.9 µA), 6-terminal XSON6 package (SOT1115, 0.9 × 1.0 × 0.35 mm), Schmitt-trigger noise immunity, IOFF backflow prevention, and guaranteed operation from –40 °C to +125 °C.

Technical Context

This device implements a single-stage combinational logic function: one data input (A), one active-low enable (E), and dual complementary outputs (1Y, 2Y). Its Schmitt-trigger inputs accept slow-rising signals and reject noise up to ±100 mV hysteresis margin depending on VCC.

The IOFF circuit disables outputs and limits leakage to ±0.75 µA when VCC = 0 V, enabling safe hot-insertion and multi-rail partial power-down. Propagation delay ranges from 1.0 ns (VCC = 3.3 V, CL = 5 pF) to 33.6 ns (VCC = 0.8 V, CL = 30 pF), scaling predictably with load and supply voltage.

FAQ

Can 74AUP1G19GN,132 operate with VCC = 1.2 V while accepting 3.3 V input signals?

Yes. The device supports VCC from 0.8 V to 3.6 V and has overvoltage-tolerant inputs rated to 3.6 V regardless of VCC level. At VCC = 1.2 V, VIH is 0.70 × VCC = 0.84 V and VIL is 0.25 × VCC = 0.30 V, enabling reliable detection of 3.3 V logic levels without level shifting.

What is the maximum capacitive load the outputs can drive while maintaining specified tpd?

The propagation delay is characterized up to CL = 30 pF across all VCC ranges. At VCC = 3.3 V, tpd remains ≤7.4 ns for CL = 30 pF. Driving loads >30 pF increases delay nonlinearly and may violate setup/hold margins in high-speed synchronous designs; external buffering is recommended beyond this limit.

How does the IOFF feature behave when VCC ramps down during system shutdown?

IOFF activates automatically when VCC falls below ~0.2 V. Output leakage is limited to ±0.75 µA even with VI or VO held at 3.6 V, preventing reverse current flow into powered-down rails. This protects upstream drivers and avoids unintended activation of downstream loads during power sequencing.

Is the 74AUP1G19GN,132 pin-compatible with other 6-pin XSON logic devices from Nexperia?

No. While SOT1115 (0.9 × 1.0 mm) shares the same terminal count and pad layout as other Nexperia XSON6 packages like SOT886 and SOT1202, the pin mapping differs: 74AUP1G19GN uses Pin 1=A, Pin 2=GND, Pin 3=E, Pin 4=2Y, Pin 5=VCC, Pin 6=1Y - unique to this decoder function and not interchangeable with inverters or buffers.
