Product details
Overview
74LVC1G240GW-Q100 from Nexperia is a single-channel automotive-grade inverting buffer/line driver with 3-state output, featuring output enable (OE) control, ±24 mA drive strength at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It operates across 1.65 V to 5.5 V supply and supports mixed-voltage level translation between 3.3 V and 5 V systems in engine control units and body electronics.
For engineers reviewing the 74LVC1G240GW-Q100 datasheet, 74LVC1G240GW-Q100 pinout, 74LVC1G240GW-Q100 application, or 74LVC1G240GW-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, -40 °C to +125 °C operating range, TSSOP5 (SOT353-1) package, and compatibility with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36.
Technical Context
This device implements a single inverting logic gate with tristate output control via an active-high OE input. Its Schmitt-trigger inputs accept slow-rising signals and tolerate overvoltage up to 5.5 V regardless of VCC, enabling robust interfacing in noisy automotive environments.
The IOFF circuit ensures bidirectional isolation during partial power-down by disabling output current flow when VCC = 0 V, preventing backfeed damage. Propagation delay ranges from 0.5 ns (min) to 8.7 ns (max) depending on VCC and load, with enable/disable times under 12 ns across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables operation in 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple CMOS/TTL loads or moderate PCB traces. |
| Propagation Delay | 0.5 ns (min) to 4.6 ns (max) at VCC = 3.0–3.6 V, CL = 50 pF - Supports high-speed digital signaling in real-time control paths. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Ensures safe hot-insertion and partial power-down in modular ECUs. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows direct connection to 5 V microcontrollers while powered from 3.3 V rails. |
| Ambient Temperature Range | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets stringent automotive ESD immunity requirements for board-level reliability. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-pin, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active-HIGH control: HIGH forces Y into high-impedance state; enables bus sharing and power gating. |
| 2 (A) | Inverting data input | Accepts 3.3 V/5 V logic; Schmitt-trigger input provides hysteresis for noise margin against EMI in vehicle harnesses. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output drivers; must be low-inductance connection in ECU PCB layout. |
| 4 (Y) | Inverting 3-state output | Drives inverted A signal when OE = LOW; enters high-Z when OE = HIGH to prevent bus contention. |
| 5 (VCC) | Positive supply | Power rail for internal logic and output stage; decoupling capacitor required within 1 cm for stable switching. |
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 protection | Blocks reverse current flow when VCC is off, eliminating need for external isolation diodes in multi-rail modules. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs even at VCC = 1.65 V, enabling seamless interface between legacy 5 V sensors and modern low-voltage MCUs. |
| Schmitt-trigger input thresholds | Hysteresis ≥ 0.3 V typical ensures reliable switching despite slow edges from long cables or resistive pull-ups. |
| JEDEC-compliant voltage interfaces | Fully supports 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) logic families. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G240DRYR | Industrial grade (-40 °C to +85 °C); no AEC-Q100 qualification; identical pinout and electrical specs except temperature range. | Not suitable for under-hood or safety-critical modules requiring automotive qualification. | Select only for non-automotive or cabin-only applications where cost optimization outweighs qualification requirements. |
| 74LVC1G04GW-Q100 | Same AEC-Q100 Grade 1 rating and TSSOP5 package but lacks 3-state output and OE input; fixed inverting buffer only. | Cannot support bus-sharing or dynamic output disable; requires redesign if tristate functionality is essential. | Use only when output enable is unnecessary and board space allows removal of OE control logic. |

FAQ
What is the maximum allowable input voltage when VCC = 1.65 V?
The 74LVC1G240GW-Q100 accepts input voltages up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Table 9 (Recommended Operating Conditions). This overvoltage tolerance enables direct interfacing with 5 V peripherals while powered from 1.65 V–1.95 V rails, eliminating external level-shifting components in mixed-voltage designs.
Does this device support hot insertion or live board swapping?
Yes-the integrated IOFF circuit actively disables output current flow when VCC = 0 V, limiting backfeed current to ±2 μA (per Table 7). This feature satisfies hot-swap requirements in modular automotive ECUs where boards may be inserted or removed while other system rails remain active, preventing latch-up or damage to upstream drivers.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger action provides input hysteresis of ≥0.3 V typical, meaning the rising and falling input thresholds differ significantly-e.g., VIH ≈ 2.0 V and VIL ≈ 0.8 V at VCC = 3.3 V. This prevents oscillation or false triggering caused by slow-rising signals from long harnesses or EMI-induced ringing, making it ideal for crankshaft/camshaft sensor interfaces near ignition systems.
Can the 74LVC1G240GW-Q100 drive a 50 pF capacitive load at 10 MHz?
Yes-dynamic characteristics in Table 8 specify propagation delay ≤4.6 ns and enable/disable times ≤7 ns at CL = 50 pF and VCC = 3.0–3.6 V. With CPD = 25 pF (enabled) and 6 pF (disabled), total dynamic power remains below 1 mW at 10 MHz, well within the 250 mW Ptot limit. Layout best practices (short traces, local decoupling) are recommended for signal integrity.
