Product details
Overview
74LVC2G240GT,115 from Nexperia is a dual inverting buffer/line driver with 3-state outputs, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, ±24 mA output drive at VCC = 3.0 V, IOFF circuitry for partial power-down protection, and operates across -40 °C to +125 °C. Used in bus interface and signal conditioning circuits in industrial control modules.
For engineers reviewing the 74LVC2G240GT,115 datasheet, 74LVC2G240GT,115 pinout, 74LVC2G240GT,115 application, or 74LVC2G240GT,115 equivalent, key selection criteria include 3-state enable timing (ten ≤ 4.8 ns), supply voltage range (1.65–5.5 V), 5 V-tolerant inputs, IOFF compliance, and XSON8 package footprint constraints.
Technical Context
This device implements two independent inverting buffers, each with active-low 3-state enable (1OE, 2OE) controlling high-impedance output states. Schmitt-trigger inputs ensure robust operation with slow-rising signals and provide hysteresis of typically 0.3 V at VCC = 3.3 V.
IOFF functionality disables both outputs when VCC = 0 V, blocking backflow current up to ±2 mA, enabling hot-swap and mixed-voltage system interoperability. The logic function table confirms inversion (nA → nY) and high-Z state activation on OE HIGH.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-supply operation across LVC logic families and enables direct interfacing with 3.3 V and 5 V systems |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS inputs without external buffering |
| Propagation Delay | tpd ≤ 5.0 ns at VCC = 5.5 V - ensures sub-5 ns signal path latency for high-speed digital control loops |
| Enable/Disable Time | ten ≤ 4.8 ns, tdis ≤ 4.6 ns at VCC = 5.5 V - guarantees fast bus arbitration and dynamic output control in time-critical applications |
| Input Voltage Tolerance | Inputs rated to 5.5 V - allows safe connection to 5 V sources while powered from 1.8 V or 3.3 V rails |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents damaging back-current during power sequencing or partial shutdown |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor drives |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8-terminal surface-mount package measuring 1.0 mm × 1.95 mm × 0.5 mm, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| VCC | Positive supply rail | Primary power input; IOFF protection activates only when VCC = 0 V |
| 2A | Data input for second buffer | Accepts 0–5.5 V signals regardless of VCC value; Schmitt-triggered |
| 2Y | Inverted output of second buffer | Active-low inverted copy of input 2A; enters high-Z when 2OE = HIGH |
| 1A | Data input for first buffer | Accepts 0–5.5 V signals regardless of VCC value; Schmitt-triggered |
| 1OE | Active-low enable for first buffer | Drives 1Y into high-impedance state when logic HIGH; referenced to GND |
| GND | Circuit ground reference | 0 V return path for all I/O and supply currents; required for IOFF and ESD protection |
Key Features
| Feature | Design Value |
|---|---|

| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis at 3.3 V, rejecting noise on slow edges from mechanical switches or long traces |
| IOFF partial power-down | Blocks >99.9% of back-current during VCC ramp-down, preventing latch-up in hot-plug interfaces |
| High noise immunity | CMOS input structure with 2000 V HBM ESD rating ensures reliability in electrically noisy industrial environments |

FAQ
Does the 74LVC2G240GT,115 support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs and limits back-current to ±2 μA when VCC = 0 V, enabling safe insertion/removal in live backplanes. This feature is verified per JEDEC JESD78 and tested at 5.5 V applied to inputs during power-off conditions.
Can inputs be driven with 5 V signals while VCC = 1.8 V?
Yes. All inputs tolerate up to 5.5 V regardless of VCC level, confirmed by static characteristics tables showing VIH/VIL limits valid across 1.65–5.5 V supply range. No external clamping diodes are required.
What is the maximum capacitive load the 74LVC2G240GT,115 can drive reliably?
It reliably drives up to 50 pF loads, as validated in dynamic characterization (Table 10). At VCC = 3.3 V and CL = 50 pF, tpd remains ≤4.6 ns and waveform integrity is maintained per Fig. 3 test setup with RL = 500 Ω.
Is the XSON8 package (SOT833-1) compatible with standard reflow profiles?
Yes. SOT833-1 complies with IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its 0.5 mm profile and copper-leadframe construction ensure uniform thermal transfer during lead-free soldering.
