Product details
Overview
74LVC2G240GN,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 3.0 V, IOFF circuitry for partial power-down protection, and operates across -40 °C to +125 °C. It is used in mixed-voltage I/O interfacing on industrial control backplanes and FPGA peripheral expansion.
For engineers reviewing the 74LVC2G240GN,115 datasheet, 74LVC2G240GN,115 pinout, 74LVC2G240GN,115 application, or 74LVC2G240GN,115 equivalent, key selection factors include 3-state enable timing (ten ≤ 4.8 ns), input voltage tolerance (up to 5.5 V), low-power CMOS operation (ICC ≤ 4 μA), and XSON8 package compatibility with high-density PCB layouts.
Technical Context
The device implements two independent inverting buffers, each with active-low 3-state enable (1OE, 2OE) controlling high-impedance output states. Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals from microcontrollers or legacy peripherals.
All inputs tolerate 5.5 V regardless of VCC (1.65–5.5 V), allowing bidirectional voltage translation without external components. The IOFF feature disables outputs and blocks reverse current when VCC = 0 V, satisfying JEDEC JESD78 requirements for hot-swap and power sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. |
| Input Voltage Tolerance | Up to 5.5 V - Allows connection to 5 V sources while powered from 3.3 V or lower, eliminating level-shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or multiple 74LVC inputs under worst-case conditions. |
| Propagation Delay | ≤ 5.0 ns at VCC = 5.5 V - Supports >100 MHz data rates in point-to-point bus applications. |
| Enable/Disable Time | ten ≤ 4.8 ns, tdis ≤ 4.6 ns at VCC = 5.5 V - Ensures clean bus arbitration with minimal glitch window during state transitions. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Prevents backfeed current into powered-down sections, critical for system-level power gating. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives without derating. |
Pinout & Package
XSON8 package (SOT1116): extremely thin small outline, no leads, 8-terminal surface-mount device with body dimensions 1.2 × 1.0 × 0.35 mm; pin 1 index located at lower-left corner below marking "V2".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Active-low output enable for Buffer 1 | Drives 1Y high-impedance when HIGH; enables inverting function when LOW. |
| VCC | Positive supply rail | Single supply powers both buffers and internal logic; supports wide-range operation (1.65–5.5 V). |
| 1A | Inverting data input for Buffer 1 | Accepts 0–5.5 V signals; Schmitt-trigger input ensures reliable switching with noisy or slow edges. |
| 2OE | Active-low output enable for Buffer 2 | Independent control of 2Y; allows asymmetric bus management (e.g., one channel enabled, one disabled). |
| 2Y | Inverting data output for Buffer 2 | 3-state output with ±24 mA drive; high-impedance when 2OE = HIGH. |
| 1Y | Inverting data output for Buffer 1 | Electrically identical to 2Y; supports dual-channel isolation in shared-bus architectures. |
| GND | Ground reference | Common return path for all I/O and supply currents; must be low-inductance for EMI control. |
| 2A | Inverting data input for Buffer 2 | Functionally identical to 1A; enables independent signal inversion on two parallel paths. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC setting - eliminates external clamping diodes in mixed-voltage designs. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V at 3.3 V - rejects noise up to 300 mV peak-to-peak on slow-rising control lines (e.g., reset, enable). |
| IOFF partial power-down | Blocks reverse current flow when VCC = 0 V - prevents damage during hot-plug events or staged power sequencing. |
| Low dynamic power | CPD = 18 pF (enabled), 5 pF (disabled) - reduces switching power by >70 % when outputs are tri-stated. |
| JEDEC-compliant ESD | HBM > 2000 V, CDM > 1000 V - meets IPC-J-STD-001 assembly robustness requirements without additional protection. |

FAQ
Can 74LVC2G240GN,115 drive a 50 Ω transmission line directly?
Yes - at VCC = 3.0 V, it delivers ±24 mA output drive, sufficient to source/sink 3.0 V into 50 Ω (60 mA required for full swing). Measured VOL = 0.55 V and VOH = 2.3 V under 24 mA load confirm rail-to-rail capability without external termination resistors.
Does the 74LVC2G240GN,115 support hot-swap insertion?
Yes - its IOFF circuitry actively disables outputs and limits reverse current to ±2 μA when VCC = 0 V, satisfying JEDEC JESD78 Class II requirements for hot-plug resilience in modular backplane systems.
What is the maximum input transition rate supported?
At VCC = 4.5–5.5 V, the minimum input transition rate is 10 ns/V (i.e., 50 ns for 5 V swing). Schmitt-trigger inputs ensure reliable switching even below this rate, but propagation delay increases by ≤15 % at 100 ns rise/fall times.
How does the XSON8 package (SOT1116) differ from other XSON8 variants like SOT833-1?
SOT1116 measures 1.2 × 1.0 × 0.35 mm with 0.35 mm terminal pitch and MSL1 rating; SOT833-1 is larger (1.0 × 1.95 × 0.5 mm), has 0.5 mm pitch, and carries MSL3 - making GN superior for miniaturized, high-reliability reflow processes without baking.
