Product details
Overview
74LVC2G240GF,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 1.65 V to 5.5 V supply. It is used in bidirectional bus interface circuits in industrial control I/O modules.
For engineers reviewing the 74LVC2G240GF,115 datasheet, 74LVC2G240GF,115 pinout, 74LVC2G240GF,115 application, or 74LVC2G240GF,115 equivalent, key selection criteria include 3-state timing (enable/disable delays ≤5.9 ns), 5 V-tolerant inputs, IOFF compliance, and XSON8 package thermal performance in space-constrained PCB layouts.
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 input thresholds provide hysteresis (ΔV ≈ 0.3–0.8 V depending on VCC), enabling robust operation with slow-rising signals from microcontrollers or sensors.
All inputs tolerate up to 5.5 V regardless of VCC, supporting mixed-voltage interfacing without external level shifters. The IOFF feature disables outputs and blocks backflow current when VCC = 0 V, satisfying JEDEC JESD78 requirements for hot-swap and partial-power-down systems.
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 legacy 5 V systems |
| Input voltage tolerance | Up to 5.5 V - enables direct connection to 5 V TTL or CMOS outputs without clamping diodes |
| Output drive strength | ±24 mA at VCC = 3.0 V - drives standard 50 Ω transmission lines or multiple 74LVC inputs under load |
| Propagation delay | ≤4.6 ns at VCC = 3.0–3.6 V - ensures sub-5 ns signal path timing for high-speed digital control buses |
| IOFF leakage current | ±2 μA max at VCC = 0 V - prevents damaging back-current during power sequencing in multi-rail systems |
| Operating temperature | −40 °C to +125 °C - qualified for extended industrial and automotive under-hood environments |
| ESD rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 system-level ESD robustness requirements |
Pinout & Package
XSON8 package (SOT1089): plastic extremely thin small outline, no leads, 8-terminal surface-mount, body dimensions 1.35 mm × 1.0 mm × 0.35 mm, wettable flank terminals for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for first inverting buffer; LOW enables output, HIGH forces high-impedance state |
| 2 | VCC | Positive supply rail; powers internal logic and output drivers; decoupling required within 2 mm |
| 3 | 1A | Inverting data input for first buffer; Schmitt-triggered, 5 V tolerant |
| 4 | 2OE | Active-low enable for second inverting buffer; independent control from 1OE |
| 5 | 2Y | Inverting output for second buffer; 3-state capable, ±24 mA sink/source at 3.0 V |
| 6 | 1Y | Inverting output for first buffer; electrically isolated from 2Y when both OEs are HIGH |
| 7 | GND | Reference ground; must be low-inductance connection to minimize switching noise coupling |
| 8 | 2A | Inverting data input for second buffer; identical electrical characteristics to 1A |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65 V to 5.5 V enables use in battery-powered (1.8 V), mixed-voltage (3.3 V/5 V), and legacy 5 V systems |
| 5 V tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC - eliminates need for external level translators in mixed-domain interfaces |
| IOFF partial power-down | Blocks current flow between powered and unpowered sections during hot-insertion or rail sequencing |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis - rejects noise on slow edges from mechanical switches, sensors, or long traces |
| High noise immunity | CMOS input structure with >40% VCC noise margin and >2000 V HBM ESD protection improves field reliability |

FAQ
What is the maximum output current per channel at 3.3 V supply?
At VCC = 3.3 V, the 74LVC2G240GF,115 delivers ±24 mA per output channel under DC conditions, verified per static characteristics Table 7. This drive strength supports direct connection to 50 Ω transmission lines or fan-out to up to 10 standard 74LVC inputs without external buffering.
Does this device support hot-plug operation with powered-backplane buses?
Yes - the integrated IOFF circuitry actively disables outputs and limits backflow current to ±2 μA when VCC = 0 V, meeting JEDEC JESD78 requirements for hot-swap compatibility. This protects upstream drivers during insertion into live backplanes or modular systems.
Can the Schmitt-trigger inputs handle slow-rising signals from mechanical switches?
Yes - Schmitt-trigger hysteresis is ≥0.3 V across all VCC operating ranges, providing noise margins that reliably debounce mechanical switch bounce and reject EMI on long traces. Input transition rate specification (10–20 ns/V) confirms robust operation with rise/fall times up to 1 μs.
Is the XSON8 package (SOT1089) compatible with standard reflow profiles?
Yes - the SOT1089 package is qualified for IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Its wettable flank design enables automated optical inspection of solder joints, and its 0.35 mm profile supports low-profile assembly in ultra-thin devices.
