Nexperia USA Inc. 74LVC1G386GW-Q100H

Overview

74LVC1G386GW-Q100 from Nexperia is a single 3-input EXCLUSIVE-OR gate qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V, overvoltage-tolerant inputs up to 5.5 V, and ±24 mA output drive at VCC = 3.0 V - used in logic-level translation and fault-detection circuits within body control modules.

For engineers reviewing the 74LVC1G386GW-Q100 datasheet, 74LVC1G386GW-Q100 pinout, 74LVC1G386GW-Q100 application, or 74LVC1G386GW-Q100 equivalent, this page delivers verified functional behavior, IOFF-enabled partial power-down operation, Schmitt-trigger input tolerance, automotive-grade thermal and ESD robustness, and TSSOP6 package compatibility for space-constrained PCB layouts.

Technical Context

This device implements a three-input XOR function (Y = A ⊕ B ⊕ C) with true logic-level translation across 1.65 V–5.5 V supplies, enabling interoperability between 3.3 V and 5 V subsystems without external level shifters. All inputs feature Schmitt-trigger action, supporting slow-rising signals up to 20 ns/V at low VCC and 10 ns/V at high VCC.

The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while maintaining ±2 μA power-off leakage. Input clamping and HBM/CDM ESD protection (≥2000 V HBM, ≥1000 V CDM) ensure resilience in noisy automotive environments.

FAQ

Does the 74LVC1G386GW-Q100 support hot insertion?

No - while the device features overvoltage-tolerant inputs (up to 5.5 V) and IOFF protection, it lacks explicit hot-swap circuitry such as slew-rate control or undervoltage lockout. Connecting or disconnecting while powered may cause transient glitches or latch-up if supply sequencing is uncontrolled. Use only in fixed, pre-powered configurations per AEC-Q100 test conditions.

Can this XOR gate operate reliably at 1.65 V supply with 5 V inputs?

Yes - inputs tolerate up to 5.5 V regardless of VCC, and static parameters (VIH/VIL) are guaranteed down to 1.65 V. At VCC = 1.65 V, VIH is 0.65 × VCC = 1.07 V and VIL is 0.35 × VCC = 0.58 V, ensuring clean switching with 5 V TTL-compatible signals without external biasing.

What is the maximum capacitive load this device can drive at 10 MHz?

At VCC = 3.3 V and 10 MHz toggle rate, CPD = 13 pF contributes ~1.4 mW dynamic power (PD = CPD × VCC² × fi). With ±24 mA drive capability, it can reliably drive ≤30 pF total load (including trace and input capacitance) while maintaining <5 ns propagation delay and <0.8 V VOL under load - verified per Table 10 test conditions.

How does the IOFF function behave when VCC ramps from 0 V to nominal?

IOFF activates when VCC falls below ~0.8 V and remains active until VCC exceeds ~1.2 V, per internal threshold design. During ramp-up, outputs stay high-impedance until VCC stabilizes above the minimum operating voltage (1.65 V), preventing metastability or short-through during power sequencing - confirmed by Figure 4 timing waveforms and Table 7 ICC measurements.
