Nexperia USA Inc. 74LVC2G125GN,115

Overview

74LVC2G125GN,115 from Nexperia is a dual 3-state bus buffer/line driver with independent output-enable inputs (1OE, 2OE), operating from 1.65 V to 5.5 V supply, supporting mixed-voltage translation between 3.3 V and 5 V systems, featuring ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity - used in bidirectional data bus isolation in industrial microcontroller interfaces.

For engineers reviewing the 74LVC2G125GN,115 datasheet, 74LVC2G125GN,115 pinout, 74LVC2G125GN,115 application, or 74LVC2G125GN,115 equivalent, this page delivers verified package mapping (SOT1116 XSON8), terminal-level functional roles, JEDEC-compliant voltage translation capability, and real-world timing specs including 2.3 ns typical propagation delay at 3.3 V - critical for high-density PCB layout and mixed-supply signal integrity validation.

Technical Context

The device implements two independent non-inverting buffers, each with active-low 3-state control (1OE/2OE), enabling selective bus loading and isolation. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - essential for hot-swap and partial-power-down system architectures.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), tolerating slow-rising signals and rejecting noise on legacy or long-trace buses. Input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V logic even when powered at 1.65 V–2.7 V, satisfying JESD8-7/8C compliance across all supported supply ranges.

FAQ

What is the maximum clock frequency supported by the 74LVC2G125GN,115?

The device does not operate as a clock buffer but as a level-translating bus buffer. Its propagation delay is 2.3 ns typical at 3.3 V, enabling reliable operation with digital signals up to ~100 MHz (based on 10%–90% rise time ≤2.5 ns). It is not characterized for jitter or phase noise, and should not be used in clock distribution paths.

Can the 74LVC2G125GN,115 safely interface a 5 V microcontroller with a 1.8 V FPGA?

Yes - its inputs tolerate up to 5.5 V regardless of VCC voltage, and it operates down to 1.65 V. When powered at 1.8 V, it correctly interprets 5 V logic-high inputs and outputs 1.8 V logic levels, making it suitable for unidirectional 5 V → 1.8 V translation without external components.

Does the 74LVC2G125GN,115 require external pull-up or pull-down resistors on its OE pins?

No - the OE inputs are CMOS-compatible and have negligible leakage (<±0.1 μA). However, to ensure defined states during power-up or reset, it is recommended to tie 1OE and 2OE to VCC via 100 kΩ resistors or drive them actively from MCU GPIOs configured as open-drain or push-pull with known startup state.

How does the IOFF feature behave when VCC is ramping during power-up?

IOFF activates only when VCC drops to 0 V; during power-up ramp, the device behaves as a standard buffer once VCC exceeds ~0.8 V. To avoid undefined output states during ramp, assert OE pins LOW only after VCC stabilizes above 1.65 V - confirmed by power-on reset circuitry or supervisor IC.
