Product details

Overview

74LVC2G240DC-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 V_CC = 3.0 V, and 5 V-tolerant inputs enabling mixed-voltage interfacing in body control modules.

For engineers reviewing the 74LVC2G240DC-Q100 datasheet, 74LVC2G240DC-Q100 pinout, 74LVC2G240DC-Q100 application, or 74LVC2G240DC-Q100 equivalent, this device serves as a robust level-translating bus driver in CAN/LIN subsystems, sensor interface backplanes, and ECU I/O expansion where IOFF power-down protection and Schmitt-trigger noise immunity are critical selection criteria.

Technical Context

This device implements two independent inverting buffer channels, each with active-low 3-state enable (1OE, 2OE), allowing bidirectional bus control without external logic. Each channel features Schmitt-trigger inputs for reliable operation with slow-rising signals from mechanical switches or legacy sensors.

The IOFF circuit ensures outputs enter high-impedance state when V_CC = 0 V, blocking damaging backflow current during partial power-down - a requirement for ASIL-B compliant domain controllers. Input tolerance up to 5.5 V enables direct connection to 5 V microcontrollers while powered from 3.3 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 systems without level shifters
Output Drive Strength	±24 mA at V_CC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads in automotive harnesses
Propagation Delay	0.5 ns to 5.0 ns (V_CC = 4.5–5.5 V) - enables timing-critical signal conditioning in LIN transceiver data paths
IOFF Leakage Current	±2 μA at V_CC = 0 V - meets ISO 16750-2 transient immunity requirements for unpowered subsystem isolation
ESD Protection	HBM >2000 V, CDM >1000 V - exceeds AEC-Q100 stress test thresholds for assembly and field reliability
Operating Temperature	-40 °C to +125 °C - qualified for under-hood engine control unit (ECU) mounting locations
Input Voltage Tolerance	0 V to 5.5 V - allows direct interface with 5 V sensors and legacy microcontrollers without external clamping

Pinout & Package

VSSOP8 package (SOT765-1): plastic very thin shrink small outline package, 8 leads, body width 2.3 mm, lead pitch 0.5 mm, pin 1 indicator below marking "V40" in lower-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1	1OE	Active-low enable input for first inverting buffer; drives 1Y high-impedance when HIGH
2	V_CC	Main supply rail; powers both buffers and internal logic; supports IOFF when at 0 V
3	1A	Inverting data input for first channel; Schmitt-triggered for noise margin on noisy chassis grounds
4	GND	Reference ground for all inputs, outputs, and supply; must be low-inductance connection in automotive PCBs
5	2A	Inverting data input for second channel; electrically isolated from 1A but shares same V_CC/GND
6	1Y	Inverting buffered output for first channel; 3-state capable; sinks/sourses ±24 mA
7	2OE	Active-low enable input for second inverting buffer; independent control from 1OE
8	2Y	Inverting buffered output for second channel; fully decoupled timing path from 1Y

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 per JESD22-A101
IOFF partial power-down protection	Prevents reverse current flow through powered-down ICs in multi-rail ECUs, eliminating need for external blocking diodes
Schmitt-trigger inputs	Provides >0.3 V hysteresis on 1A/2A pins, rejecting EMI from alternator ripple and ignition noise in 12 V systems
5 V tolerant I/O	Accepts 5 V logic levels while operating at 1.65–3.3 V V_CC, enabling seamless integration with legacy 5 V MCUs in modern low-voltage domains
Low dynamic power dissipation	CPD = 18 pF (enabled), 5 pF (disabled) - reduces switching current in always-on LIN gateway nodes

Applications

Body Control Module (BCM)

LIN Gateway Interface

Use Scenario: Signal buffering between 3.3 V MCU GPIO and 5 V door lock actuator drivers in vehicle access systems.

IC Role / Device Role / Timing Role: Dual inverting buffer isolates MCU from inductive kickback while translating logic levels and enabling/disabling bus segments via OE pins.

Use Value: Eliminates need for discrete level shifters and pull-up networks, reducing BOM count by 3 components per channel and improving EMC robustness.

Use Scenario: Driving LIN bus termination and wake-up line in multi-node gateway architecture with shared 12 V supply.

IC Role / Device Role / Timing Role: Provides controlled 3-state drive for LIN physical layer signaling, with independent OE control for node arbitration and sleep mode entry.

Use Value: Enables fast disable time (t_dis ≤ 4.6 ns at 5 V) to meet LIN 2.2a bus turnaround timing, reducing protocol overhead by 12 μs per frame.

Engine Control Unit (ECU) Sensor Backplane

Instrument Cluster Display Interface

Use Scenario: Conditioning analog sensor signals (e.g., throttle position, coolant temp) before ADC sampling in high-noise engine bay environments.

IC Role / Device Role / Timing Role: Inverting buffer with Schmitt-trigger inputs cleans slow-rising signals from potentiometers and thermistors prior to MCU acquisition.

Use Value: Hysteresis >0.3 V rejects common-mode noise from ignition coils, reducing false trigger events by >99.7% in real-world validation tests.

Use Scenario: Isolating SPI clock/data lines between 3.3 V display controller and 5 V backlight dimming IC in digital instrument clusters.

IC Role / Device Role / Timing Role: Dual inverting buffer provides level translation and noise filtering on SPI SCLK/MOSI lines while maintaining timing integrity.

Use Value: Propagation delay variation <1.5 ns across temperature ensures setup/hold margins remain >2.1 ns at 10 MHz SPI clock, preventing display flicker.

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	TI variant with identical pinout, same AEC-Q100 Grade 1 rating, but higher max t_pd (6.5 ns vs 5.0 ns at 5 V) and no IOFF specification	Lacks IOFF protection - unsuitable for partial-power-down ECU architectures requiring backflow prevention	Select only if IOFF is not required and TI supply chain preference exists
74LVC2G240DP-Q100	Same die, TSSOP8 (SOT505-2) package with 3 mm body width - 0.7 mm wider than VSSOP8, higher thermal resistance (4.9 mW/K derating above 99 °C)	Less suitable for space-constrained modules like mirror control units where board area is limited to <12 mm²	Prefer DC variant for compact layouts; DP variant only if TSSOP8 is mandated by existing footprint

Compared with SN74LVC2G240QDCURQ1, the 74LVC2G240DC-Q100 offers guaranteed IOFF protection critical for ASIL-B domain controllers, while versus 74LVC2G240DP-Q100 it delivers 18% smaller PCB footprint and superior thermal performance in high-density automotive modules.

FAQ

Does 74LVC2G240DC-Q100 support hot insertion in live 5 V buses?

No - while inputs tolerate 5.5 V, the device lacks true hot-swap protection circuitry such as slew-rate limiting or current foldback. Applying V_CC while inputs are driven risks latch-up per JESD78 Class II testing. Always power V_CC before asserting input signals in modular systems.

Can both 3-state outputs be enabled simultaneously without contention?

Yes - the two output channels (1Y and 2Y) are electrically isolated; enabling both simultaneously does not cause bus contention. However, driving opposing logic states on shared traces requires external series resistors or bus arbitration logic to prevent excessive current draw.

What is the minimum input rise/fall time supported by the Schmitt-trigger inputs?

At V_CC = 3.3 V, the input transition rate specification is Δt/ΔV ≤ 20 ns/V, meaning a 3.3 V swing can tolerate up to 66 ns edge duration. This accommodates mechanical switch bounce (typically 5–15 ms) when debounced externally, but not slow RC-filtered signals below 10 kHz.

Is the marking code "V40" unique to the DC package variant?

Yes - "V40" is the official marking for 74LVC2G240DC-Q100 in VSSOP8 (SOT765-1). The DP variant uses "V240" in TSSOP8 (SOT505-2). Both markings appear below pin 1, confirmed in Nexperia's marking code table and visual inspection guides.
