Product details
Overview
74LVC1G18GW-Q100 from Nexperia is an automotive-grade 1-of-2 non-inverting demultiplexer with 3-state deselected outputs, operating from 1.65 V to 5.5 V supply, supporting mixed-voltage translation between 3.3 V and 5 V logic domains, and featuring Schmitt-trigger inputs for noise immunity in harsh environments such as engine control units and body electronics.
For engineers reviewing the 74LVC1G18GW-Q100 datasheet, 74LVC1G18GW-Q100 pinout, 74LVC1G18GW-Q100 application, or 74LVC1G18GW-Q100 equivalent, this device is selected for its AEC-Q100 Grade 1 qualification, IOFF partial power-down capability, ±24 mA output drive at 3.0 V, and guaranteed operation from −40 °C to +125 °C in automotive signal routing systems.
Technical Context
This demultiplexer routes a single input (A) to one of two outputs (1Y or 2Y) based on the logic state of the select input (S), with the unselected output placed in high-impedance (Z) state. Its non-inverting data path preserves signal polarity, and Schmitt-trigger inputs tolerate slow-rising signals common in noisy automotive harnesses.
The IOFF circuit ensures backflow current is blocked when VCC = 0 V, enabling safe hot insertion and partial power-down in multi-rail systems. Input overvoltage tolerance up to 5.5 V allows direct interfacing with 5 V TTL sources even when powered at 1.65 V–3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - supports wide-battery automotive systems and mixed-voltage board designs without level shifters |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood and transmission control module deployment |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple CMOS inputs or small capacitive loads |
| Propagation delay | 3.0 ns typical (VCC = 3.3 V) - enables reliable timing in sub-100 MHz digital signal distribution paths |
| IOFF leakage | ±2 μA max at VCC = 0 V - prevents damaging back-current during system power sequencing |
| Input overvoltage tolerance | 5.5 V absolute max - permits 5 V logic inputs while operating at 1.8 V or 2.5 V core rails |
| ESD protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements for assembly and field operation |
Pinout & Package
TSSOP6 plastic thin shrink small outline package (SOT363-2), 6-lead, body width 1.25 mm, lead pitch 0.65 mm, designed for high-density automotive PCB layouts with thermal and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Select input | Controls output routing: LOW → A routed to 1Y; HIGH → A routed to 2Y |
| 2 (GND) | Ground reference | 0 V return path for all internal logic and output drivers; must be low-impedance in automotive EMI environments |
| 3 (A) | Data input | Non-inverting input signal source; accepts 3.3 V or 5 V logic levels regardless of VCC |
| 4 (2Y) | Output 2 | Active-high output enabled when S = HIGH; otherwise high-impedance (3-state) |
| 5 (VCC) | Supply voltage | Primary power rail; IOFF protection activates automatically when VCC = 0 V |
| 6 (1Y) | Output 1 | Active-high output enabled when S = LOW; otherwise high-impedance (3-state) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across −40 °C to +125 °C ambient, including thermal cycling and humidity testing |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is off, enabling safe hot-swap and multi-rail sequencing |
| Schmitt-trigger inputs | Provides hysteresis (typically 0.3 V at VCC = 3.3 V), rejecting noise on long harness traces or switch debouncing paths |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V input signals independent of VCC, eliminating need for external level translators in mixed-voltage systems |
| Low dynamic power dissipation | CPD = 28.8 pF - minimizes switching power in always-on vehicle modules like gateway ECUs |
Applications
| Engine Control Unit (ECU) Signal Routing | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-of-2 demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G18DBVR | Industrial grade (−40 °C to +85 °C), no AEC-Q100 qualification, identical pinout and electrical specs | Not suitable for under-hood or safety-critical modules; acceptable for cabin infotainment or non-safety accessories | Select when automotive qualification is unnecessary and cost sensitivity outweighs environmental robustness requirements |
| 74LVC1G19GW-Q100 | Inverting demultiplexer function; same package, temp range, and IOFF support but inverted output logic | Requires complementary firmware logic to maintain signal polarity; unsuitable where non-inverting path is mandated by protocol | Choose only if system architecture accommodates inverted enable behavior and avoids redesign of upstream control logic |
Compared with SN74LVC1G18DBVR, the 74LVC1G18GW-Q100 adds guaranteed operation at +125 °C and AEC-Q100 stress validation-critical for engine bay placement-while 74LVC1G19GW-Q100 trades functional compatibility for inversion, limiting drop-in replacement in polarity-sensitive timing paths.

FAQ
What is the maximum clock/data frequency supported by the 74LVC1G18GW-Q100?
The device does not operate as a clocked sequential element but as a combinational demultiplexer. Its propagation delay is 3.0 ns typical at VCC = 3.3 V, enabling reliable operation with input signal edges up to ~150 MHz in terms of transition rate, provided load capacitance remains ≤30 pF and rise/fall times meet the specified Δt/ΔV limits.
Can the 74LVC1G18GW-Q100 be used with a 1.8 V supply and 3.3 V input signals?
Yes. The inputs are overvoltage tolerant up to 5.5 V, so 3.3 V logic signals may be applied while VCC = 1.8 V. VIH and VIL thresholds scale with VCC (e.g., VIH ≥ 0.65×VCC), ensuring correct interpretation of 3.3 V HIGH/LOW states even at minimum supply.
Does the 74LVC1G18GW-Q100 support hot-swap or live-insertion scenarios?
Yes. The IOFF circuit actively disables outputs and blocks back-current when VCC = 0 V, allowing safe insertion into a powered-backplane system. This feature complies with JEDEC JESD78 latch-up immunity and is validated per AEC-Q100 stress tests for automotive hot-swap reliability.
How does the Schmitt-trigger input improve noise immunity in automotive applications?
Schmitt-trigger inputs provide hysteresis-typically ~0.3 V at VCC = 3.3 V-so the input threshold differs for rising (VIH) and falling (VIL) transitions. This prevents multiple toggles caused by slow or noisy edges on long wiring harnesses, especially near ignition systems or alternators, ensuring clean signal registration without external filtering.
