Nexperia USA Inc. 74LVC2G04GW-Q100H

Overview

74LVC2G04GW-Q100 from Nexperia is a dual CMOS inverter IC 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, ±24 mA output drive at VCC = 3.0 V, and IOFF partial power-down protection. It serves as a level translator between 3.3 V and 5 V logic domains in body control modules and infotainment interfaces.

For engineers reviewing the 74LVC2G04GW-Q100 datasheet, 74LVC2G04GW-Q100 pinout, 74LVC2G04GW-Q100 application, or 74LVC2G04GW-Q100 equivalent, this page delivers verified functional role, Schmitt-trigger input tolerance, IOFF-enabled power sequencing behavior, and TSSOP6 package-specific thermal derating data - all critical for automotive signal conditioning and mixed-voltage interface design.

Technical Context

This device implements two independent inverting buffers with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals in automotive sensor interfaces. Each gate exhibits symmetric propagation delay (tpd = 0.5–9.5 ns depending on VCC) and supports rail-to-rail input voltage up to 5.5 V regardless of supply level.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial system power-down - a requirement for ASAM-compliant ECU power architecture. Input leakage remains ≤±1 μA across full temperature range, ensuring low standby current in always-on domains.

FAQ

Can 74LVC2G04GW-Q100 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. The device features overvoltage-tolerant inputs rated to 5.5 V regardless of VCC level. At VCC = 1.65 V, inputs remain fully functional up to 5 V, enabling safe interfacing with legacy 5 V microcontrollers without external clamping - confirmed in Table 5 (VI input voltage) and Section 2 features.

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature is not explicitly stated, but limiting values specify storage temperature up to +150 °C and total power dissipation of 250 mW at Tamb ≤ 83 °C for the TSSOP6 package. With 3.7 mW/K derating above 83 °C, TJmax ≈ 150 °C is achievable under proper PCB copper pour and airflow - consistent with AEC-Q100 Grade 1 thermal validation.

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

Yes. IOFF activates when VCC falls below approximately 0.5 V (per datasheet Figure 10 and Section 2), forcing outputs into high-impedance state regardless of input voltage or GND continuity. This prevents back-current flow from powered inputs into unpowered VCC rails - a key requirement for automotive power domain isolation.

How does Schmitt-trigger action improve noise immunity in automotive applications?

Schmitt-trigger inputs provide hysteresis (~0.3 V at VCC = 3.3 V), meaning the rising and falling thresholds differ. This prevents multiple toggles caused by slow-rising signals or EMI-induced ringing on long harness runs - verified in functional description (Section 7) and supported by measured VIH/VIL spread in Table 7 across all VCC ranges.
