Nexperia USA Inc. 74LVC2G07GW,125

Overview

74LVC2G07GW,125 from Nexperia is a dual CMOS buffer with open-drain outputs, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and operates across 1.65 V to 5.5 V supply. Used in I²C bus pull-up interfaces, GPIO expansion, and mixed-voltage signal conditioning.

For engineers reviewing the 74LVC2G07GW,125 datasheet, 74LVC2G07GW,125 pinout, 74LVC2G07GW,125 application, or 74LVC2G07GW,125 equivalent, this device serves as a robust, low-power, voltage-tolerant buffer for bidirectional interface bridging, bus arbitration, and active-low open-drain signaling in industrial control and embedded peripherals.

Technical Context

The 74LVC2G07GW,125 implements two independent non-inverting buffers, each with an open-drain output requiring external pull-up. Its Schmitt-trigger inputs accept slow-rising signals and tolerate input voltages up to 5.5 V regardless of VCC, enabling direct interfacing with 5 V TTL while powered from 1.65–3.3 V rails. The IOFF feature disables both outputs when VCC = 0 V, blocking backflow current during hot insertion or partial system shutdown.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), and supports operation from –40 °C to +125 °C. Propagation delay ranges from 0.5 ns (VCC = 5 V) to 8.4 ns (VCC = 1.65 V, –40 °C to +125 °C), with typical power dissipation capacitance of 6.5 pF at 3.3 V.

FAQ

Can 74LVC2G07GW,125 drive a 10 kΩ pull-up resistor on a 5 V bus while powered from 3.3 V?

Yes. With VCC = 3.3 V, the device sinks up to 24 mA at VO = 0.55 V (typical), yielding a maximum valid pull-up resistance of ~200 Ω for full logic-low margin. For 10 kΩ, the output will not reach true 0 V - instead, it settles near 0.55 V, which may violate 5 V TTL LOW threshold (0.8 V). Use ≤2.2 kΩ for reliable 5 V bus operation.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes. IOFF engages when VCC falls below approximately 0.8 V, disabling both outputs and limiting OFF-state leakage to ±2 μA maximum. This occurs without external control signals and remains active until VCC rises above ~1.2 V, ensuring safe hot-swap behavior during power sequencing or brownout conditions.

Is the Schmitt-trigger hysteresis specified in the datasheet?

No. The datasheet confirms Schmitt-trigger action at all inputs but does not publish hysteresis voltage (ΔV) values. However, measured input thresholds (VIH/VIL) show consistent separation - e.g., at VCC = 3.3 V, VIH(min) = 2.0 V and VIL(max) = 0.8 V - implying ≥1.2 V hysteresis, sufficient to reject noise spikes up to 1.2 V peak-to-peak.

What is the maximum capacitive load the 74LVC2G07GW,125 can drive while maintaining 10 ns propagation delay?

At VCC = 3.3 V, tpd ≤ 4.7 ns (max) with CL = 50 pF per output, per Table 10 test conditions. Driving >50 pF increases delay nonlinearly - e.g., 100 pF raises tpd to ~7.2 ns. For strict 10 ns budget, loads up to 75 pF are acceptable, but layout parasitics must be minimized to avoid exceeding total CL.
