Nexperia USA Inc. 74LVC2G86GXX

Overview

74LVC2G86 from Nexperia is a dual 2-input EXCLUSIVE-OR gate IC with wide supply range (1.65 V to 5.5 V), overvoltage-tolerant inputs (up to 5.5 V), and IOFF partial power-down capability. It enables level translation between 3.3 V and 5 V logic domains and features Schmitt-trigger inputs for noise immunity in noisy industrial control signal paths.

For engineers reviewing the 74LVC2G86 datasheet, 74LVC2G86 pinout, 74LVC2G86 application, or 74LVC2G86 equivalent, this device supports mixed-voltage interface design, low-power portable instrumentation, and robust digital signal conditioning where input rise/fall time tolerance and backflow current prevention are critical.

Technical Context

The 74LVC2G86 implements two independent XOR logic functions using CMOS technology, each accepting two inputs (1A/1B, 2A/2B) and delivering complementary outputs (1Y, 2Y). Its IOFF circuit actively disables outputs during power-down to block damaging backflow current when VCC = 0 V.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling reliable operation with slow-rising signals up to 20 ns/V (VCC = 1.65–2.7 V) or 10 ns/V (VCC = 2.7–5.5 V), while propagation delay ranges from 0.6 ns (VCC = 5.5 V) to 9.9 ns (VCC = 1.65 V) across temperature and voltage conditions.

FAQ

Can the 74LVC2G86 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device's overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level, including at the minimum 1.65 V supply. This is verified per Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions) in the official Nexperia datasheet Rev. 17. Input clamping current remains within ±50 mA limits, and VIH/VIL thresholds scale correctly to ensure logic recognition.

Does the IOFF feature work when VCC is disconnected but GND remains connected?

Yes. IOFF activates when VCC = 0 V (or near 0 V), forcing outputs into high-impedance state even if GND is maintained. Measured IOFF leakage is ≤±2 μA per Table 7, preventing backflow current from live inputs or outputs into the unpowered IC. This behavior is guaranteed across −40 °C to +125 °C.

What is the maximum capacitive load the 74LVC2G86 can drive at 3.3 V while maintaining tpd ≤ 5 ns?

At VCC = 3.3 V and Tamb = 25 °C, the typical propagation delay is 2.3 ns with 30 pF load (Table 10 test condition). With 50 pF load, tpd increases to ≤4.7 ns (Table 8). Therefore, the device reliably drives up to 50 pF while staying within 5 ns, assuming standard PCB trace capacitance and no additional series resistance.

Is the 74LVC2G86 qualified for automotive applications per AEC-Q100?

No. While rated for −40 °C to +125 °C operation, the 74LVC2G86 is not AEC-Q100 qualified. Nexperia explicitly states in Section 15 ("Legal information") that non-automotive qualified products "are not suitable for automotive use" unless expressly marked as such. For automotive use, select the AEC-Q100 qualified 74LVC2G86-Q100 variant.
