Nexperia USA Inc. 74LVC2G86DC,125

Overview

74LVC2G86DC,125 from Nexperia is a dual 2-input EXCLUSIVE-OR gate in VSSOP8 package (SOT765-1), operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity and IOFF circuitry enabling partial power-down mode. It supports mixed-voltage translation between 3.3 V and 5 V logic domains and is rated for -40 °C to +125 °C operation.

For engineers reviewing the 74LVC2G86DC,125 datasheet, 74LVC2G86DC,125 pinout, 74LVC2G86DC,125 application, or 74LVC2G86DC,125 equivalent, this device serves as a low-power, voltage-tolerant logic gate for level-shifting, parity generation, and digital signal conditioning in space-constrained industrial and embedded control systems.

Technical Context

This CMOS logic IC implements two independent XOR functions with rail-to-rail input tolerance up to 5.5 V and guaranteed switching down to 1.65 V VCC. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals in noisy environments.

The IOFF feature disables outputs when VCC = 0 V, preventing backflow current during hot-insertion or partial system power-down-critical for I²C bus isolation, FPGA configuration sequencing, and modular power management architectures.

FAQ

Can 74LVC2G86DC,125 operate with 1.8 V supply while accepting 3.3 V inputs?

Yes. The device is specified for VCC = 1.65 V to 5.5 V and features overvoltage-tolerant inputs rated to 5.5 V regardless of supply voltage. At VCC = 1.8 V, inputs up to 3.3 V are safely accepted and correctly interpreted, enabling direct 3.3 V → 1.8 V level translation without external circuitry.

Does the IOFF feature require external control signals?

No. IOFF is fully automatic and requires no external enable/disable pin. When VCC drops to 0 V (e.g., during hot-swap or partial power-down), the internal circuitry detects the loss of supply and disables both outputs within nanoseconds, preventing back-current flow through the device.

What is the maximum capacitive load this device can drive reliably?

At VCC = 3.3 V and Tamb = 25 °C, the device maintains specified VOH/VOL with CL ≤ 50 pF and output frequency ≤ 10 MHz. For heavier loads (>50 pF), propagation delay increases linearly; derating curves in the datasheet show tpd increases by ~0.1 ns/pF beyond 30 pF at VCC = 3.3 V.

Is the VSSOP8 package (SOT765-1) compatible with standard reflow profiles?

Yes. The SOT765-1 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1) and supports standard lead-free reflow profiles with peak temperatures up to 260 °C. Its 0.5 mm lead pitch and 2.3 mm body width are compatible with automated optical inspection and AOI-based solder joint verification.
