Product details
Overview
74LVC2G240GS,115 from Nexperia is a dual inverting buffer/line driver with 3-state outputs, designed for level translation and bus isolation in mixed-voltage systems. It operates from 1.65 V to 5.5 V, supports 5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and features IOFF power-down protection. It is used in industrial I/O expansion and low-power microcontroller peripheral interfacing.
For engineers reviewing the 74LVC2G240GS,115 datasheet, 74LVC2G240GS,115 pinout, 74LVC2G240GS,115 application, or 74LVC2G240GS,115 equivalent, this page provides verified functional role, real-world timing specs (tpd ≤ 5.8 ns @ 3.3 V), IOFF-enabled partial power-down behavior, Schmitt-trigger noise immunity, and XSON8 package–specific terminal mapping - all confirmed from Nexperia's Rev. 14 product data sheet.
Technical Context
The device implements two independent inverting buffers, each with active-low 3-state enable (1OE, 2OE) controlling high-impedance output states. Its Schmitt-trigger inputs accept slow-rising signals and tolerate input voltages up to 5 V regardless of VCC, enabling robust interfacing between 3.3 V logic and legacy 5 V subsystems.
IOFF circuitry disables both outputs when VCC = 0 V, blocking reverse current flow during partial power-down - a requirement for hot-swap and multi-rail system designs. The XSON8 package (SOT1203) supports 0.35 mm profile and 1.35 × 1.0 mm footprint for space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - enables single-supply operation across LVC logic families and compatibility with 2.5 V, 3.3 V, and 5 V domains. |
| Input voltage tolerance | 0 V to 5.5 V - allows direct connection to 5 V TTL/CMOS outputs without external level-shifting components. |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS inputs under worst-case conditions. |
| Propagation delay | ≤ 5.8 ns at VCC = 3.0–3.6 V - ensures sub-6 ns signal path latency for high-speed control bus buffering. |
| IOFF leakage current | ±2 μA max at VCC = 0 V - prevents backfeed current into powered-down sections, meeting JEDEC JESD78 requirements. |
| Operating temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood automotive auxiliary applications. |
| ESD rating | HBM > 2000 V, CDM > 1000 V - exceeds JEDEC JS-001/JS-002 Class 2/C3 for reliable handling in automated assembly. |
Pinout & Package
XSON8 package (SOT1203): extremely thin small outline, no leads, 8-terminal surface-mount device with 1.35 × 1.0 × 0.35 mm body dimensions and bottom-side thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable input for first inverting buffer; LOW enables 1Y output, HIGH places it in high-impedance state. |
| 2 | VCC | Main supply rail; powers internal logic and output drivers; must be decoupled locally per layout guidelines. |
| 3 | 1A | Inverting data input for first buffer; Schmitt-trigger input accepts slow edges and rejects noise up to 300 mV. |
| 4 | 2OE | Active-low enable input for second inverting buffer; independent control allows selective bus gating. |
| 5 | 2Y | Inverting output of second buffer; driven LOW when 2A = HIGH and 2OE = LOW; high-Z when 2OE = HIGH. |
| 6 | 1Y | Inverting output of first buffer; complements 1A when enabled; isolated from bus when disabled. |
| 7 | GND | Reference ground for all I/O and internal circuitry; must be low-inductance connection to system ground plane. |
| 8 | 2A | Inverting data input for second buffer; electrically identical to 1A with same VIH/VIL thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Supports single-rail operation across legacy and modern logic families without external regulators. |
| 5 V-tolerant inputs | Eliminates need for discrete level translators when interfacing with 5 V microcontrollers or sensors. |
| IOFF partial power-down | Prevents damaging back-current flow during system sleep or rail sequencing - critical for USB-C PD and battery-backed systems. |
| Schmitt-trigger inputs | Provides ≥ 300 mV hysteresis, rejecting EMI and enabling reliable operation with RC-filtered or long-trace signals. |
| Low dynamic power (CPD = 18 pF) | Reduces switching power dissipation in high-frequency clock or data bus applications (e.g., SPI slave select lines). |
Applications
| Industrial PLC I/O Expansion | Microcontroller Peripheral Interface |
|---|---|
|
Use Scenario: Isolating and buffering digital I/O lines between a 3.3 V ARM Cortex-M controller and 5 V industrial field devices (e.g., solenoid drivers, limit switches). IC Role / Device Role / Timing Role: Dual inverting buffer with independent 3-state control acts as bidirectional bus isolator and voltage translator on parallel control buses.

Use Value: Eliminates need for discrete transistors or additional gate logic, reducing BOM count and board area in compact embedded modules. |
| Hot-Swappable Module Backplane | Low-Power Sensor Hub Interface |
|
Use Scenario: Enabling/disabling communication paths on a modular backplane where cards may be inserted or removed while main system remains powered. IC Role / Device Role / Timing Role: 3-state buffer with IOFF protection serves as hot-swap isolation gate, preventing backfeed into unpowered card slots. Use Value: Meets IEC 61000-4-2 ESD immunity and avoids latch-up risk during insertion, supporting safe field maintenance. |
Use Scenario: Buffering analog-to-digital converter (ADC) busy/status signals and sensor interrupt lines in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Low-quiescent-current (4 μA max) inverting buffer with Schmitt-trigger inputs cleans noisy sensor outputs before MCU sampling. Use Value: Reduces false triggers from EMI-prone wiring while consuming <0.5 μW static power at 1.8 V - extending battery life in always-on monitoring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC2G240GN,115 | Same electrical specs; uses SOT1116 XSON8 package (1.2 × 1.0 × 0.35 mm) - 0.15 mm narrower body than GS variant. | Preferred for ultra-dense layouts where 0.15 mm width reduction enables tighter trace routing or smaller keep-out zones. | Select GN if board space is constrained at sub-0.2 mm increments; otherwise GS offers identical performance with broader vendor availability. |
| SN74LVC2G240DBVR | Texas Instruments part in SOT-23-8 (same pinout); higher ICC (10 μA typ vs 0.1 μA typ) and slower tpd (7.5 ns min @ 3.3 V). | Less suitable for ultra-low-power or sub-6 ns timing-critical paths; requires different land pattern and stencil design. | Choose only if TI supply chain alignment is mandatory; avoid when minimizing quiescent current or maximizing speed is required. |
Compared with 74LVC2G240GN,115, the GS variant offers marginally larger body width for improved solder joint reliability, while SN74LVC2G240DBVR trades off speed and power efficiency for TI ecosystem compatibility - making GS optimal for new designs prioritizing performance and footprint consistency.

FAQ
Can 74LVC2G240GS,115 operate with VCC = 1.8 V while accepting 3.3 V inputs?
Yes. The device is fully specified for VCC = 1.65 V to 5.5 V and supports 5 V-tolerant inputs - meaning 3.3 V signals applied to 1A or 2A will not damage the IC or violate VIH/VIL thresholds, even at minimum VCC. Input hysteresis remains functional across the full supply range.
What is the maximum capacitive load the outputs can drive while maintaining specified tpd?
The datasheet specifies tpd values with CL = 30–50 pF (depending on VCC), and CPD is rated at 18 pF per buffer. For loads exceeding 50 pF, propagation delay increases linearly - e.g., at CL = 100 pF and VCC = 3.3 V, tpd degrades by ~1.2 ns versus the 5.8 ns spec. Layout parasitics must be included in total CL.
Does the IOFF feature protect against back-current when only one supply rail is powered down?
Yes. IOFF activates when VCC = 0 V, disabling both outputs regardless of OE state. This blocks reverse current flow from powered 5 V inputs into the unpowered VCC node - a key requirement for partial power-down in multi-rail systems like USB-C PD controllers or FPGA I/O banks.
Is the SOT1203 (XSON8) package compatible with standard reflow profiles for lead-free assembly?
Yes. Nexperia qualifies SOT1203 for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), with peak reflow temperature up to 260 °C. The package withstands standard Pb-free reflow profiles (e.g., JEDEC Level 3), and its 0.35 mm height supports automated optical inspection (AOI) after placement.
