Product details
Overview
74LVC2G240DP-Q100 from Nexperia is a dual inverting 3-state buffer/line driver qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V, ±24 mA output drive at VCC = 3.0 V, and 5 V-tolerant inputs enabling mixed-voltage level translation in CAN/LIN bus interface circuits.
For engineers reviewing the 74LVC2G240DP-Q100 datasheet, 74LVC2G240DP-Q100 pinout, 74LVC2G240DP-Q100 application, or 74LVC2G240DP-Q100 equivalent, this device serves as a robust, low-power, Schmitt-trigger-equipped logic translator for automotive body control modules, infotainment power sequencing, and sensor signal conditioning where IOFF-enabled partial power-down and high noise immunity are required.
Technical Context
This device implements two independent inverting buffers, each with active-low 3-state enable (1OE, 2OE), enabling bidirectional bus isolation in automotive sub-systems. Each channel features Schmitt-trigger inputs for reliable operation with slow-rising signals from mechanical switches or analog sensors.
IOFF circuitry ensures outputs enter high-impedance state during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and multi-rail power architectures. Input tolerance up to 5.5 V allows direct interfacing with legacy 5 V microcontrollers while powered from 3.3 V or 2.5 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-rail operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS/TTL loads |
| Input Voltage Tolerance | 0 V to 5.5 V - enables 5 V input acceptance while VCC ≥ 1.65 V, eliminating external level shifters |
| Propagation Delay | 0.5 ns to 5.0 ns (VCC = 4.5–5.5 V) - ensures timing compliance in 25 MHz+ digital control loops |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents damaging back-current during system power sequencing |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - withstands handling and in-vehicle electrostatic events |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-pin, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm, RoHS-compliant, moisture sensitivity level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for first inverting buffer; drives 1Y to high-impedance when HIGH |
| 2 | VCC | Main supply rail; powers both buffers and internal logic; decoupling capacitor required |
| 3 | 1A | Inverting data input for first channel; Schmitt-triggered for noise margin on slow edges |
| 4 | GND | Reference ground for all I/O and internal circuitry; must be low-inductance connection |
| 5 | 2A | Inverting data input for second channel; electrically isolated from 1A path |
| 6 | 1Y | Inverted, 3-state output of first channel; sinks/sourcing up to ±24 mA |
| 7 | 2OE | Active-low enable for second inverting buffer; independent control from 1OE |
| 8 | 2Y | Inverted, 3-state output of second channel; fully decoupled from 1Y switching noise |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive applications requiring operation up to +125 °C ambient |
| IOFF partial power-down protection | Prevents reverse current flow when VCC = 0 V, enabling safe hot-plug and rail sequencing |
| Schmitt-trigger inputs | Provides > 0.3 V hysteresis, rejecting noise on switch debouncing or sensor analog-to-digital interfaces |
| 5 V-tolerant I/O | Accepts 5 V inputs while powered from 1.65–3.3 V rails - eliminates discrete level-shifter components |
| Low dynamic power dissipation | CPD = 18 pF (enabled), 5 pF (disabled) - reduces switching losses in battery-powered ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G240QDCURQ1 | VSSOP8 (SOT765-1) package; 2.3 mm body width; identical electrical specs and AEC-Q100 Grade 1 rating | Higher board density; tighter layout constraints due to smaller pad pitch and thermal mass | Select for space-constrained PCBs where thermal derating above 99 °C is acceptable |
| 74LVC2G125DP-Q100 | Non-inverting 3-state buffer; same pinout, package, and AEC-Q100 qualification; lacks inversion logic | Used where signal polarity must be preserved (e.g., clock distribution, non-inverted enable paths) | Choose only if system logic requires true-level pass-through rather than inversion |
Compared with SN74LVC2G240QDCURQ1, the 74LVC2G240DP-Q100 offers better thermal dissipation in TSSOP8 but occupies more board area; versus 74LVC2G125DP-Q100, it delivers inverted logic essential for active-low enable schemes without adding external inverters.

FAQ
What is the maximum allowable input voltage when VCC = 0 V?
The absolute maximum input voltage is -0.5 V to +6.5 V per Table 5, regardless of VCC state. When VCC = 0 V, the IOFF circuit blocks current flow, and input clamping diodes limit VI to ±50 mA - allowing safe 5 V input application during power-down sequences without damage.
Can 74LVC2G240DP-Q100 drive a 50 Ω transmission line directly?
Yes: at VCC = 3.0 V, it delivers ±24 mA output drive, supporting 50 Ω termination to VCC/2 (e.g., 1.5 V mid-point) with VOH ≈ 2.3 V and VOL ≈ 0.55 V - sufficient for LVCMOS25/LVCMOS33 signaling integrity up to 25 MHz without external drivers.
How does the Schmitt-trigger input improve noise immunity?
It provides ~0.3–0.4 V hysteresis (VIH − VIL) depending on VCC, meaning rising/falling thresholds differ significantly - rejecting transient noise spikes ≤ 0.3 V and ensuring clean, bounce-free transitions from mechanical switches, potentiometers, or unfiltered sensor outputs in automotive ECU environments.
Is the TSSOP8 (SOT505-2) package lead-free and RoHS compliant?
Yes: the SOT505-2 package uses 100% matte tin lead finish, complies with EU RoHS Directive 2011/65/EU and China RoHS, and meets JEDEC J-STD-020 moisture sensitivity level 1 - allowing standard reflow profiles without baking pre-assembly.
