Nexperia USA Inc. 74LVC1G86GX,125

Overview

74LVC1G86GX,125 from Nexperia is a single 2-input EXCLUSIVE-OR gate in X2SON5 (SOT1226-3) package, operating from 1.65 V to 5.5 V supply, supporting mixed-voltage interfacing between 3.3 V and 5 V systems, featuring IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and guaranteed operation from –40 °C to +125 °C for industrial timing and logic-level translation.

For engineers reviewing the 74LVC1G86GX,125 datasheet, 74LVC1G86GX,125 pinout, 74LVC1G86GX,125 application, or 74LVC1G86GX,125 equivalent, this device serves as a compact, low-power XOR function for signal conditioning, parity generation, and digital state comparison in space-constrained embedded control and interface circuits where voltage-level flexibility and power-state isolation are required.

Technical Context

This CMOS logic gate implements the Boolean Y = A ⊕ B function with rail-to-rail input tolerance up to 5.5 V and guaranteed switching down to 1.65 V VCC. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and multi-rail system integrity.

Propagation delay ranges from 0.5 ns (min) to 6.5 ns (max) across 1.65–5.5 V VCC and –40 °C to +125 °C, with input transition rate support up to 20 ns/V at lower voltages and 10 ns/V above 2.7 V, enabling reliable operation in both legacy TTL-compatible and modern low-voltage digital subsystems.

FAQ

Can 74LVC1G86GX,125 operate with 1.8 V supply and interface to 5 V inputs?

Yes. The device is fully specified from 1.65 V to 5.5 V VCC and features overvoltage-tolerant inputs rated to 5.5 V regardless of supply voltage. At 1.8 V VCC, VIH is guaranteed ≥1.2 V and VIL ≤0.45 V, allowing safe, direct connection to 5 V logic outputs without external level-shifting circuitry.

Does the IOFF feature work when VCC is disconnected but inputs remain biased?

Yes. When VCC = 0 V, the IOFF circuit automatically disables the output (Y), presenting high-impedance behavior and limiting IOFF leakage to ±2 μA maximum - preventing back-current flow from live inputs into the unpowered device, which protects downstream circuitry during hot-swap or partial power-down sequences.

What is the maximum capacitive load this device can drive at 10 MHz with 3.3 V supply?

At 3.3 V VCC and 10 MHz toggle rate, the dynamic power dissipation is governed by CPD = 25 pF. With 25 pF load, total dynamic power is ~2.7 mW. The device reliably drives ≤30 pF loads per datasheet test conditions, supporting typical PCB traces and one additional LVC input without timing degradation or excessive heating in X2SON5 package.

Is 74LVC1G86GX,125 qualified for automotive applications?

No. This part is specified for industrial temperature range (–40 °C to +125 °C) but is not AEC-Q200 qualified, lacks automotive-specific reliability testing, and carries no automotive qualification statement in its official Nexperia documentation. For automotive use, select Nexperia's automotive-grade variants such as 74LVC1G86GW-Q100 (TSSOP5, AEC-Q200 qualified).
