Product details
Overview
74LVC2G240GD,125 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 power-down protection, and operates across 1.65 V to 5.5 V supply. It is used in bus interface circuits requiring bidirectional voltage translation and controlled output enable.
For engineers reviewing the 74LVC2G240GD,125 datasheet, 74LVC2G240GD,125 pinout, 74LVC2G240GD,125 application, or 74LVC2G240GD,125 equivalent, key selection criteria include 3-state timing (enable/disable delays ≤5.9 ns), 5 V tolerant I/O, IOFF current <±2 μA at VCC = 0 V, and compatibility with TSSOP8, VSSOP8, and XSON8 packages including SOT996-2.
Technical Context
The device implements two independent inverting buffers, each with active-low 3-state enable (1OE, 2OE). Outputs enter high-impedance OFF-state when respective OE is HIGH, enabling bus sharing. Schmitt-trigger inputs accept slow-rising signals and tolerate input voltages up to 5 V regardless of VCC setting.
IOFF circuitry actively disables outputs during power-down, blocking backflow current even when VCC = 0 V and I/O pins are biased to 5 V. The design complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36 across its full 1.65–5.5 V operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports mixed-voltage system interfacing without external level shifters |
| Input Voltage Tolerance | 0 V to 5.5 V - enables direct connection to 5 V TTL/CMOS sources while powered from 1.8 V or 3.3 V rails |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple LVC loads |
| Propagation Delay | 0.5 ns to 5.8 ns (VCC = 3.0–3.6 V) - ensures sub-6 ns signal path latency for high-speed control buses |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents damaging back-current during hot-swap or partial power-down sequences |
| Operating Temperature | −40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G240DBVR | Same logic function and pinout; VSSOP8 (SOT765-1) package; slightly higher tpd (max 6.5 ns @ 2.7 V) | Identical functional behavior but different thermal resistance (4.9 mW/K derating above 99 °C vs. 4.2 mW/K for SOT996-2) | Select for legacy VSSOP8 footprint compatibility or where board space permits larger body width (2.3 mm vs. 1.35 mm) |
| 74LVC2G240GT,125 | Same XSON8 form factor (SOT833-1); identical electrical specs; body size 1.0 × 1.95 × 0.5 mm vs. 1.35 × 1.0 × 0.35 mm | Higher profile (0.5 mm vs. 0.35 mm) limits use in ultra-thin portable designs; same thermal derating (3.1 mW/K above 68 °C) | Select when 1.95 mm length is acceptable and standard XSON8 land pattern is preferred over SOT996-2's asymmetric layout |

FAQ
What is the maximum allowable input voltage when VCC = 1.8 V?
The 74LVC2G240GD,125 supports 5 V tolerant inputs: VI may reach up to 5.5 V regardless of VCC setting. This allows safe interfacing with 5 V TTL or CMOS outputs even when powered from 1.65–1.95 V rails, eliminating external level-shifting components and reducing BOM count.
Does the device support hot-swap operation?
Yes - the integrated IOFF circuit actively disables outputs and limits leakage to ±2 μA when VCC = 0 V, preventing damaging back-current from live I/O lines into a powered-down device. This enables safe insertion/removal in systems with live backplanes or multi-rail power domains.
How does the Schmitt-trigger input improve system reliability?
Schmitt-trigger inputs provide hysteresis (≥0.3 V at VCC = 3.3 V), rejecting noise on slow-rising/falling edges and preventing false triggering from EMI, crosstalk, or unterminated traces. This is critical in industrial and automotive environments where signal integrity cannot rely solely on clean PCB layout.
Can both buffers be enabled simultaneously without contention?
Yes - each buffer has independent active-low enable inputs (1OE and 2OE), allowing simultaneous or staggered activation. Since both outputs (1Y and 2Y) are unidirectional and non-overlapping in function, no bus contention occurs. The 3-state architecture ensures isolation when either buffer is disabled.
