Product details
Overview
74LVC1G18GV-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 qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for use in engine control units and body electronics.
For engineers reviewing the 74LVC1G18GV-Q100 datasheet, 74LVC1G18GV-Q100 pinout, 74LVC1G18GV-Q100 application, or 74LVC1G18GV-Q100 equivalent, key selection criteria include its IOFF-enabled partial power-down capability, Schmitt-trigger input tolerance for slow-edge signals, ±24 mA output drive at 3.0 V, 3.0 ns typical propagation delay at 3.3 V, and SC-74 (SOT457) 6-pin surface-mount package.
Technical Context
This device implements a single-pole double-throw (SPDT) data routing function: input A is routed to either 1Y or 2Y based on select input S state (LOW → 1Y active; HIGH → 2Y active), while the unselected output enters high-impedance (Z) state. The 3-state outputs enable bus sharing in multi-source systems.
All inputs feature Schmitt-trigger action for noise immunity and compatibility with slow-rising signals, and the IOFF circuit actively disables outputs during power-down to prevent backflow current-critical for hot-swap and partial-power-down architectures 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 both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (A→Y) | 3.0 ns typical at VCC = 3.3 V - Supports signal routing in sub-100 MHz digital control paths such as sensor multiplexing or configuration switching. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC loads or moderate capacitive loads (e.g., PCB traces, small buffers) without external buffering. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Ensures safe isolation during system sleep modes, preventing current leakage into powered-down subsystems. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows 5 V inputs to be safely applied even when VCC = 1.65 V, enabling robust voltage-level translation. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive applications including transmission control and ADAS sensor hubs. |

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 except temp range and IOFF characterization. | Not suitable for under-hood or safety-critical automotive locations; acceptable for cabin infotainment or rear-seat entertainment modules. | Select when automotive qualification is unnecessary and cost sensitivity outweighs extended temperature margin. |
| 74LVC1G19GV-Q100 | Inverting demultiplexer (A inverted before routing); otherwise identical package, temp range, IOFF, and voltage specs. | Requires complementary logic inversion in upstream signal path; unsuitable where signal polarity must be preserved (e.g., clock distribution). | Choose only if system-level logic already accommodates inverted data; avoid for timing-critical or polarity-sensitive routes. |
Compared with SN74LVC1G18DBVR, the 74LVC1G18GV-Q100 adds guaranteed AEC-Q100 Grade 1 reliability and IOFF validation for automotive power sequencing, while 74LVC1G19GV-Q100 trades functional equivalence for polarity inversion-making the original part uniquely suited for non-inverting, high-integrity signal routing in engine and chassis domains.

FAQ
What is the maximum allowable input voltage when VCC = 1.65 V?
The 74LVC1G18GV-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. This allows 5 V signals from legacy microcontrollers or sensors to be safely applied even when the device operates at minimum 1.65 V supply-enabling mixed-voltage system interoperability without external protection circuitry.
Does this device support hot insertion or live board replacement?
Yes-the integrated IOFF circuit actively disables outputs and limits power-off leakage to ±2 μA when VCC = 0 V, preventing damaging backflow current during hot-swap events. This feature is validated per AEC-Q100 stress tests and supports safe live replacement in modular automotive control units.
Can the 74LVC1G18GV-Q100 drive a 50 pF capacitive load at 10 MHz?
Yes-its ±24 mA output drive at 3.0 V and 3.0 ns typical propagation delay ensure clean signal edges into 50 pF loads. Dynamic power dissipation is calculated as PD = CPD × VCC² × fi × N (CPD = 28.8 pF), resulting in ~3.2 μW at 10 MHz and 3.3 V, well within thermal limits of the SOT457 package.
How does the Schmitt-trigger input improve noise immunity in automotive harnesses?
Schmitt-trigger inputs provide 0.3–0.5 V hysteresis, rejecting common-mode noise and slow edge degradation typical in long automotive wiring harnesses. This ensures reliable logic-level detection of signals from switches, sensors, or LIN bus nodes-even with >100 ns rise/fall times-without false triggering or metastability.
