Product details
Overview
74AUP1G19GM,115 from Nexperia is a low-power 1-of-2 decoder/demultiplexer with 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 dual outputs when enabled and drives both outputs high when disabled-used in voltage-level-flexible logic routing for portable sensors and battery-powered microcontroller I/O expansion.
For engineers reviewing the 74AUP1G19GM,115 datasheet, 74AUP1G19GM,115 pinout, 74AUP1G19GM,115 application, or 74AUP1G19GM,115 equivalent, key selection criteria include its ultra-low ICC (≤0.9 µA), IOFF leakage (<±0.75 µA at VCC = 0 V), Schmitt-trigger noise immunity, 6-terminal XSON6 (SOT886) package, and guaranteed operation from –40 °C to +125 °C.
Technical Context
This device implements combinational logic decoding with two complementary outputs derived from a single data input A and an active-low enable E. Its Schmitt-trigger inputs tolerate slow-rising/falling signals and reject noise up to ±10 % of VCC overshoot/undershoot.
The IOFF circuit disables outputs during power-down, blocking backflow current when VCC = 0 V, making it suitable for hot-swap and partial-power-down systems. All static and dynamic parameters-including propagation delay (as low as 1.0 ns at VCC = 3.0 V, CL = 5 pF) and CPD (7.6 pF)-are fully characterized across –40 °C to +125 °C and the full 0.8–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - supports direct interface with 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (Static) | 0.9 µA at VCC = 0.8–3.6 V - enables multi-year battery life in always-on sensor nodes and wearables. |
| IOFF Leakage | ±0.75 µA at VCC = 0 V - prevents damaging back-current during system power sequencing or hot insertion. |
| Propagation Delay | 1.2 ns (min) to 4.1 ns (max) at VCC = 3.0–3.6 V, CL = 5 pF - meets timing budgets for 100+ MHz control-path demuxing. |
| Input Hysteresis | Typical 0.1 × VCC - rejects noise on slow GPIO lines in industrial or automotive environments. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor controllers. |
| ESD Rating | HBM >5000 V, CDM >1000 V - reduces field failure risk in manual assembly and handling. |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body dimensions 1.0 mm × 1.45 mm × 0.5 mm; wettable flank terminals for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | Primary logic signal source routed to both outputs when E is asserted; Schmitt-triggered for noise margin. |
| 2 (GND) | Ground reference | 0 V return path for all internal logic and output drivers; must be low-impedance for stable switching. |
| 3 (E) | Enable input (active LOW) | Controls output state: LOW enables demux action; HIGH forces 1Y and 2Y high-impedance-equivalent HIGH. |
| 4 (2Y) | Complement output | Inverted copy of A when E = LOW; driven to VOH/VOL per load and VCC; IOFF disables when VCC = 0 V. |
| 5 (VCC) | Supply voltage | Power rail for core logic and output buffers; supports 0.8–3.6 V; decoupling capacitor required near pin. |
| 6 (1Y) | True output | Non-inverted copy of A when E = LOW; electrically identical to 2Y except polarity; same drive strength and timing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA across full VCC and temperature range - eliminates thermal derating concerns in dense PCB layouts. |
| IOFF partial power-down | Output disable with VCC = 0 V and VI/VO = 0–3.6 V - enables safe interconnection between powered/unpowered subsystems. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.1 × VCC - allows reliable operation with RC-filtered or long-trace GPIO signals without external hysteresis. |
| Overvoltage-tolerant inputs | VI up to 3.6 V independent of VCC - permits interfacing with higher-voltage logic without clamping diodes. |
| Wide temperature qualification | Specified from –40 °C to +125 °C - validated for engine control modules, industrial PLCs, and outdoor IoT gateways. |
Applications
| Industrial Sensor Hub | Automotive Body Control Module |
|---|---|
|
Use Scenario: Routing MCU GPIO signals to multiple analog sensor enable lines (e.g., temperature, humidity, pressure) with shared enable control. IC Role / Device Role / Timing Role: 1-of-2 demux selects which sensor receives active-high enable while maintaining signal integrity across mixed-voltage domains. Use Value: Eliminates need for discrete MOSFET switches or larger logic ICs; reduces BOM count and board area by 40% vs. dual-buffer solution. |
Use Scenario: Distributing wake-up signals from CAN transceiver interrupt to two independent microcontroller peripherals (LIN bus controller and door lock MCU). IC Role / Device Role / Timing Role: Decoder provides synchronized, glitch-free true/complement wake pulses with sub-5 ns skew across –40 °C to +125 °C. Use Value: Ensures deterministic wake timing critical for ASAM-compliant sleep/wake protocols; IOFF prevents current leakage during deep sleep. |
| Portable Medical Monitor | Smart Home Hub Controller |
|
Use Scenario: Enabling either ECG front-end or SpO₂ LED driver from a single low-power MCU pin in a wearable patch design. IC Role / Device Role / Timing Role: Demux acts as ultra-low-power signal router with <1 µA quiescent draw-preserving battery life over multi-week operation. Use Value: Extends runtime by >12 hours per charge vs. using standard 74LVC logic; Schmitt inputs suppress noise from adjacent RF sections. |
Use Scenario: Selecting between Zigbee and Bluetooth LE radio enable lines based on active wireless protocol in a dual-radio home gateway. IC Role / Device Role / Timing Role: Dual-output demux delivers simultaneous, phase-aligned enable signals to two radios with matched propagation delay. Use Value: Reduces protocol handover latency by 3.2 ns vs. cascaded inverters; overvoltage-tolerant inputs simplify level-shifting with 3.3 V radios. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-of-2 decoder/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G19DBVR | Higher ICC (max 10 µA), no IOFF, narrower VCC range (1.65–5.5 V), no Schmitt inputs | Not suitable for partial power-down or sub-1.65 V operation; requires external noise filtering | Select only if operating strictly at 3.3 V with no power sequencing constraints and cost is primary driver. |
| 74AHC1G19GW,125 | Wider VCC (2–5.5 V), higher speed (tpd ≈ 0.8 ns), no IOFF, no Schmitt inputs, TSSOP6 package | Unsuitable for battery-powered or mixed-voltage systems; lacks hot-swap safety | Prefer for high-speed 5 V industrial control where IOFF and ultra-low power are not required. |

FAQ
Can 74AUP1G19GM,115 operate with VCC = 0.85 V?
Yes. The device is fully specified from 0.8 V to 3.6 V, including VIH/VIL thresholds, propagation delay, and output drive strength at 0.85 V. Static current remains ≤0.9 µA, and Schmitt-trigger hysteresis is maintained per datasheet Table 7 at this voltage.
What happens to outputs when VCC = 0 V and E = LOW?
When VCC = 0 V, the IOFF circuit activates regardless of E state, forcing both 1Y and 2Y into high-impedance mode with leakage ≤±0.75 µA. Outputs remain safely isolated-no current flows even if external voltages up to 3.6 V are applied to A, E, 1Y, or 2Y.
Is the XSON6 (SOT886) package compatible with reflow soldering per J-STD-020?
Yes. The SOT886 package is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). Its 0.5 mm profile and wettable flanks support automated optical inspection and high-yield assembly in fine-pitch consumer and automotive PCBs.
How does Schmitt-trigger action improve noise immunity in this device?
Schmitt-trigger inputs provide ≥0.1 × VCC hysteresis, meaning the rising threshold (VIH) is significantly higher than the falling threshold (VIL). This prevents multiple output transitions due to slow or noisy input edges-critical for reliable operation on long traces, unshielded cables, or near switching regulators.
