Nexperia USA Inc. 74LVC2G06GXZ

Overview

74LVC2G06GXZ from Nexperia is a dual CMOS inverter 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. Its -24 mA sink capability at 3.0 V enables direct interface with I²C buses and wired-AND configurations.

For engineers reviewing the 74LVC2G06GXZ datasheet, 74LVC2G06GXZ pinout, 74LVC2G06GXZ application, or 74LVC2G06GXZ equivalent, key selection criteria include open-drain drive strength, input overvoltage tolerance to 5.5 V, IOFF-enabled system-level power sequencing, and thermal-enhanced X2SON6 packaging for high-density PCB layouts.

Technical Context

This device implements two independent inverting buffers with open-drain outputs, enabling wired-logic functions and bidirectional voltage translation without external pull-ups on the output side. Each channel accepts input voltages up to 5.5 V regardless of VCC, supporting mixed-voltage interconnects.

The IOFF circuit actively disables both outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial power-down sequences. Schmitt-trigger inputs provide hysteresis (typically 0.3 V at VCC = 3.3 V), allowing robust operation with slow-rising signals from mechanical switches or legacy TTL sources.

FAQ

Can 74LVC2G06GXZ drive a 400 kbps I²C bus with 400 pF capacitance?

Yes. At VCC = 3.3 V and IO = -24 mA, VOL remains ≤ 0.55 V, satisfying I²C standard low-level voltage requirements. With typical CPD = 5.9 pF and propagation delay < 3.7 ns, it meets timing budgets for standard-mode (100 kbps) and fast-mode (400 kbps) I²C, assuming proper external pull-up sizing (e.g., 2.2 kΩ for 3.3 V).

Does the IOFF feature require external control signals?

No. IOFF is fully automatic and internally controlled: when VCC drops below approximately 0.2 V, the output transistors are disabled without any external enable/disable pin or configuration. This occurs passively during power removal or brownout, preventing back-current flow through the device.

What is the maximum allowable output load capacitance before signal integrity degrades?

The datasheet specifies CL = 50 pF in dynamic test conditions. For reliable operation beyond this, derate based on tpd increase: at VCC = 3.3 V, tpd rises ~0.3 ns per 10 pF above 50 pF. Signal rise/fall times remain within specification up to 100 pF when using 500 Ω termination and ≤2.5 ns input edges, per Figure 5 test setup.

Is the X2SON6 package (SOT1255-2) compatible with standard XSON6 reflow profiles?

Yes. SOT1255-2 shares JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and peak reflow temperature (260 °C) with other XSON6 variants. Its thinner profile (0.32 mm vs. 0.35 mm) does not require profile adjustment, but stencil aperture should be reduced by 10 % to prevent solder bridging due to tighter terminal spacing (0.30 mm pitch).
