Product details
Overview
74LVC1G157GW-Q100 from Nexperia is an automotive-grade single 2-input CMOS multiplexer with Schmitt-trigger inputs, IOFF partial power-down protection, and 1.65 V to 5.5 V supply operation. It enables level translation between 3.3 V and 5 V logic domains in vehicle body control modules, infotainment I/O expansion, and ADAS sensor interface routing. Propagation delay is as low as 0.5 ns at 5 V, output drive is ±24 mA at 3.0 V, and it operates across -40 °C to +125 °C.
For engineers reviewing the 74LVC1G157GW-Q100 datasheet, 74LVC1G157GW-Q100 pinout, 74LVC1G157GW-Q100 application, or 74LVC1G157GW-Q100 equivalent, this device is selected for mixed-voltage signal routing where AEC-Q100 Grade 1 qualification, IOFF-enabled hot-swap capability, and Schmitt-trigger noise immunity are required in automotive ECUs.
Technical Context
This device implements a single-pole double-throw (SPDT) analog/digital multiplexer function using standard CMOS logic gates with integrated Schmitt-trigger input buffers. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences in multi-rail automotive systems.
The functional truth table defines Y = I0 when S = L and Y = I1 when S = H, with no internal latching. Input voltage tolerance up to 5.5 V allows direct interfacing with legacy 5 V peripherals while powered from 1.65–3.3 V rails, satisfying JESD8-7/8C/36 compliance across all operating voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters |
| Propagation Delay (tpd) | 0.5 ns (min) at VCC = 4.5–5.5 V - enables high-speed signal routing in timing-critical automotive data paths |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures safe hot-plug operation and prevents backfeed into powered subsystems |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and transmission-control applications |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows 5 V signals to be accepted even when device is powered at 1.65 V |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive system-level ESD robustness requirements per ISO 10605 |
Pinout & Package
TSSOP6 plastic thin shrink small outline package (SOT363-2), 6-lead, body width 1.25 mm, pin pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I1) | Data input source 1 | High-side multiplexer input; accepts 0–5.5 V regardless of VCC; Schmitt-triggered for noise margin |
| 2 (GND) | Ground reference | Primary return path for all I/O and supply currents; must be low-impedance in automotive PCB layout |
| 3 (I0) | Data input source 0 | Low-side multiplexer input; identical electrical behavior to I1; used for default or backup signal path |
| 4 (Y) | Multiplexer output | Active-drive output with ±24 mA capability; IOFF disables output to high-Z when VCC = 0 V |
| 5 (VCC) | Positive supply rail | Single supply input supporting 1.65–5.5 V; powers internal logic and output stage; decoupling required |
| 6 (S) | Common select input | Controls routing: S = L selects I0 → Y; S = H selects I1 → Y; Schmitt-triggered for slow-edge immunity |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and HTOL stress |
| IOFF partial power-down mode | Automatically disables output drivers and isolates I/O pins when VCC = 0 V, preventing back-current damage |
| Schmitt-trigger inputs | Provides >0.5 V hysteresis on all inputs (I0, I1, S), enabling reliable operation with slow-rise signals (e.g., LIN bus, resistive sensors) |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals irrespective of VCC setting - eliminates need for external clamping diodes in mixed-voltage designs |
| JEDEC-compliant voltage ranges | Fully compliant with JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) |
Applications

Use Value: Guarantees clean edge transitions on sync lines despite cable-induced ringing; 5.5 V input tolerance accommodates legacy camera modules operating at 5 V. |
Use Scenario: Arbitrating between redundant radar and ultrasonic sensor trigger pulses sent to a central timing controller in parking assist systems. IC Role / Device Role / Timing Role: Deterministic signal selector with guaranteed tpd ≤5.0 ns at 125 °C - maintains precise inter-sensor timing alignment. Use Value: Preserves nanosecond-level time-of-flight accuracy required for sensor fusion algorithms; AEC-Q100 qualification ensures operation in engine bay proximity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G157DRYR | Industrial grade (-40 °C to +85 °C), same pinout and logic function but lacks AEC-Q100 qualification and IOFF circuitry | Not suitable for automotive under-hood or safety-critical modules requiring Grade 1 thermal and reliability validation | Select only for non-automotive or cabin-only applications where cost sensitivity outweighs qualification requirements |
| 74LVC1G157GV-Q100 | Identical electrical specs and AEC-Q100 Grade 1 rating, but packaged in SC-74 (SOT457) instead of TSSOP6 (SOT363-2) | Same functional performance; differs only in thermal resistance (4.1 mW/K derating above 89 °C vs. 3.7 mW/K above 83 °C for TSSOP6) | Prefer GW variant for higher power density layouts; prefer GV for legacy board compatibility with wider lead spacing |
Compared with SN74LVC1G157DRYR, the 74LVC1G157GW-Q100 adds mandatory automotive qualification and IOFF protection; compared with 74LVC1G157GV-Q100, it offers slightly better thermal derating performance in compact TSSOP6 packaging.

FAQ
Can the 74LVC1G157GW-Q100 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. The device supports overvoltage-tolerant inputs up to 5.5 V independent of VCC level. At VCC = 1.65 V, inputs I0, I1, and S may swing from 0 V to 5.5 V without damage or functional degradation, enabling seamless level translation in mixed-voltage domains.
What happens to the Y output when VCC is removed during system power-down?
When VCC drops to 0 V, the IOFF circuitry automatically places the Y output in high-impedance state, limiting leakage current to ±2 μA maximum. This prevents backflow current from other powered subsystems into the unpowered device, satisfying automotive partial power-down safety requirements.
Is the 74LVC1G157GW-Q100 compatible with 3.3 V LVTTL logic levels?
Yes. With VCC = 3.3 V, VIH is 0.7 × VCC = 2.31 V and VIL is 0.3 × VCC = 0.99 V, fully compatible with standard 3.3 V LVTTL thresholds. Output VOH exceeds 2.6 V and VOL remains below 0.55 V at 24 mA load, ensuring noise margins >0.4 V.
Does the Schmitt-trigger input affect propagation delay specifications?
No. Propagation delay (tpd) values in Table 8 are measured under standard test conditions with defined input transition rates (≤2.5 ns). Schmitt-trigger hysteresis improves noise immunity but does not alter the specified tpd min/typ/max values, which reflect worst-case gate delay through the multiplexer path.
