Product details
Overview
74LVC1G19GW-Q100 from Nexperia is an automotive-qualified 1-of-2 decoder/demultiplexer with active-low enable, delivering true (1Y) and complement (2Y) outputs from single data input A. It operates across 1.65 V to 5.5 V supply, tolerates 5.5 V inputs, provides ±24 mA output drive at 3.0 V, and features IOFF partial power-down protection. Used in automotive body control modules for signal routing between mixed-voltage subsystems.
For engineers reviewing the 74LVC1G19GW-Q100 datasheet, 74LVC1G19GW-Q100 pinout, 74LVC1G19GW-Q100 application, or 74LVC1G19GW-Q100 equivalent, this device supports voltage-level translation in 3.3 V/5 V mixed-signal domains, offers Schmitt-trigger input noise immunity, and meets AEC-Q100 Grade 1 requirements for under-hood electronics.
Technical Context
This device implements a combinational logic function: when enable (E) is LOW, it routes input A to 1Y (non-inverted) and 2Y (inverted); when E is HIGH, both outputs go HIGH regardless of A. The dual-output architecture enables simultaneous true/complement signal distribution without external inverters.
All inputs feature Schmitt-trigger action, supporting slow-rising/falling signals up to 10 ns/V transition rate (VCC ≥ 2.7 V), and IOFF circuitry disables outputs during power-down to prevent backflow current - critical for hot-swap and partial-power-down systems in automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple CMOS/TTL loads or moderate capacitive bus lines. |
| Propagation Delay | 0.5 ns to 13.1 ns - varies with VCC and temperature; 5.0 ns max at 5.5 V over -40 °C to +125 °C ensures timing predictability in real-time control paths. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - limits backflow current during system sleep modes, protecting upstream drivers and reducing standby power. |
| Ambient Temperature Range | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and transmission control unit deployment. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage sensors or legacy 5 V microcontrollers. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP6 (SOT363-2) package: plastic thin shrink small outline, 6-pin, 1.25 mm body width, 0.65 mm lead pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - A | Data input | Single-bit address/data source routed to outputs when E is active LOW; Schmitt-triggered for noise margin. |
| 2 - GND | Ground reference | 0 V return path for all internal logic and output stages; must be low-impedance for stable switching. |
| 3 - E | Enable input (active LOW) | Global control: LOW enables decoding/demux; HIGH forces both outputs HIGH - used for output gating or bus arbitration. |
| 4 - 2Y | Inverted output | Complement of A when E = LOW; open-drain capable only when externally pulled - standard push-pull CMOS output. |
| 5 - VCC | Supply voltage | Primary power rail; powers internal logic and output buffers; decoupling capacitor required near pin. |
| 6 - 1Y | True output | Non-inverted copy of A when E = LOW; matches input state with minimal delay; drives downstream logic directly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| IOFF partial power-down | Outputs automatically high-impedance when VCC = 0 V, preventing current backflow into powered sections during sleep or fault conditions. |
| Overvoltage-tolerant inputs | Accepts 0 V to 5.5 V signals regardless of VCC setting - eliminates need for external clamping diodes in mixed-voltage designs. |
| Schmitt-trigger inputs | Hysteresis > 0.3 V typical at 3.3 V - rejects noise on slow-switching signals from mechanical switches or analog sensors. |
| Wide VCC operating range | 1.65 V to 5.5 V - supports battery-backed operation down to 1.65 V and compatibility with legacy 5 V systems. |
Applications

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 |
|---|---|---|---|
| SN74LVC1G19DRYR | Industrial grade (-40 °C to +85 °C), no AEC-Q100 qualification; identical pinout and electrical specs. | Not suitable for under-hood or safety-critical automotive locations; acceptable for cabin infotainment or gateway modules. | Select when automotive qualification is unnecessary and cost sensitivity outweighs environmental ruggedness. |
| 74LVC1G19GW,115 | Same die, non-automotive variant; lacks AEC-Q100 test documentation and extended temperature validation. | Approved for commercial/industrial use only; not traceable to automotive PPAP or change control processes. | Choose for prototyping or non-automotive embedded systems where full AEC compliance is not mandated. |
Compared with SN74LVC1G19DRYR and 74LVC1G19GW,115, the 74LVC1G19GW-Q100 uniquely guarantees operation up to +125 °C with full AEC-Q100 Grade 1 test reports, IOFF validation at automotive temperature extremes, and production traceability for OEM programs - making it the only option for powertrain and chassis control nodes.

FAQ
What is the maximum allowable input voltage when VCC = 1.8 V?
The 74LVC1G19GW-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When VCC = 1.8 V, inputs may safely swing from 0 V to 5.5 V without damage or latch-up, enabling direct connection to 5 V sensors or microcontrollers without external level-shifting circuitry.
Does this device support hot insertion or live board swapping?
Yes - the IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA even if inputs remain at 5.5 V. This protects powered circuitry during hot-swap events in modular automotive ECUs and ensures compliance with IEC 61000-4-2 ESD immunity requirements.
Can both outputs drive 50 pF loads simultaneously at 10 MHz?
Yes - with VCC = 3.3 V, propagation delay remains ≤ 5.2 ns and output drive strength is ±24 mA, easily supporting 50 pF loads at 10 MHz. Power dissipation stays below 250 mW (derated above 83 °C), and CPD = 18.9 pF confirms low dynamic loading on driving sources.
Is the Schmitt-trigger hysteresis specified over temperature?
Yes - hysteresis is maintained across -40 °C to +125 °C, with typical values exceeding 0.3 V at 3.3 V supply. This ensures consistent noise rejection on slow-rising signals (e.g., from reed switches or thermistors) in all automotive operating conditions without external RC filtering.
