Nexperia USA Inc. 74LVC2G07GXZ

Overview

74LVC2G07GXZ 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 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 microcontroller interconnects.

For engineers reviewing the 74LVC2G07GXZ datasheet, 74LVC2G07GXZ pinout, 74LVC2G07GXZ application, or 74LVC2G07GXZ equivalent, key selection criteria include open-drain drive strength at 3.0 V (–24 mA), IOFF leakage < ±2 μA during power-down, input overvoltage tolerance to 5.5 V, and guaranteed operation from –40 °C to +125 °C in X2SON6 package.

Technical Context

This device implements two independent non-inverting buffers, each with an open-drain output stage enabling wired-AND logic and bidirectional bus interfacing. The Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), supporting slow-rising signals from mechanical switches or long traces.

IOFF circuitry actively disables both outputs when VCC = 0 V, blocking backflow current from powered downstream nodes - critical for hot-swap and partial-power-down systems. Input voltage range extends to 5.5 V regardless of VCC, allowing direct connection to 5 V TTL outputs while powered from 1.8 V or 3.3 V rails.

FAQ

Can 74LVC2G07GXZ drive a 10 kΩ pull-up resistor on a 3.3 V I²C bus?

Yes. At VCC = 3.3 V and IO = 3.3 V / 10 kΩ = 330 μA, the output voltage remains below 0.4 V (well within I²C VOL spec of 0.4 V). The device's –24 mA sink capability provides ample margin - typical VOL is 0.10 V at 100 μA and 0.55 V at 24 mA, ensuring reliable low-state signaling even with worst-case bus capacitance and noise.

Does the IOFF feature require external biasing or enable signals?

No. IOFF is fully automatic and requires no external control. When VCC drops to 0 V, internal circuitry disables both outputs to high-impedance state, limiting back-current to ±2 μA maximum. This occurs passively during power removal or brownout - no additional pins, resistors, or firmware intervention are needed.

Is the X2SON6 package (SOT1255-2) compatible with standard reflow profiles?

Yes. The X2SON6 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and withstands peak reflow temperatures up to 260 °C. Its thermal-enhanced construction allows full JEDEC-compliant lead-free reflow without voiding or delamination, provided stencil aperture and solder paste volume match Nexperia's recommended 0.12 mm thickness and 75% area ratio.

How does Schmitt-trigger input behavior affect timing in slow-switching applications?

Schmitt-trigger inputs introduce fixed hysteresis (~0.3 V at 3.3 V), causing asymmetric switching thresholds: VIH ≈ 2.0 V and VIL ≈ 1.7 V. This prevents chatter on slow-rising signals (e.g., from RC networks or mechanical switches) but adds negligible delay (<1 ns) versus standard CMOS inputs. Propagation delay remains tightly specified across all VCC and temperature conditions per Table 8.
