Nexperia USA Inc. 74LVC1G04GW-Q100H

Overview

74LVC1G04GW-Q100 from Nexperia is a single-channel CMOS inverter with Schmitt-trigger inputs, IOFF partial power-down protection, and AEC-Q100 Grade 1 automotive qualification. It operates from 1.65 V to 5.5 V, accepts 5.5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and supports mixed-voltage translation between 3.3 V and 5 V systems in engine control units and body electronics.

For engineers reviewing the 74LVC1G04GW-Q100 datasheet, 74LVC1G04GW-Q100 pinout, 74LVC1G04GW-Q100 application, or 74LVC1G04GW-Q100 equivalent, key selection criteria include IOFF-enabled safe power sequencing, Schmitt-trigger noise immunity for slow-rising sensor signals, automotive temperature range (–40 °C to +125 °C), TSSOP5 package footprint compatibility, and JEDEC-compliant voltage-level translation capability.

Technical Context

This device implements a single inverting logic gate with hysteresis on all inputs, enabling robust operation with slow or noisy input transitions common in automotive sensor interfaces. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and multi-rail system integrity.

The logic function is strictly inverting (A → Y), with propagation delays as low as 0.5 ns at 5.5 V and 25 °C, and static input thresholds (VIH/VIL) that scale with supply voltage per JEDEC standards JESD8-7/8-5/8C/36. Output drive strength is specified across 1.65–5.5 V, supporting direct TTL interfacing without level-shifting components.

FAQ

What is the maximum input voltage the 74LVC1G04GW-Q100 can tolerate when VCC = 1.8 V?

The device tolerates inputs up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Section 2 (Features). This overvoltage tolerance enables safe interfacing with 5 V sensors or controllers while operating from a 1.8 V supply, eliminating external clamping diodes.

Does the 74LVC1G04GW-Q100 support hot insertion in live backplane systems?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting back-current to ≤±2 μA (Table 7). This meets hot-swap requirements for modular automotive ECUs where boards may be inserted into powered chassis backplanes without disrupting upstream power rails.

Can this inverter drive a 100 pF capacitive load at 10 MHz without signal degradation?

Yes - with CPD = 14 pF (Table 8) and tpd ≤ 5.5 ns at 3.3 V, the device maintains clean edges into 100 pF loads at 10 MHz. Dynamic power dissipation remains below 1 mW (PD = CPD × VCC² × fi × N), ensuring stable operation without thermal derating.

Is the Schmitt-trigger hysteresis value fixed or supply-dependent?

Hysteresis is supply-dependent: typical ΔV = 0.35 V at VCC = 3.3 V, scaling approximately linearly with VCC per functional description and test data. This ensures consistent noise margin across the full 1.65–5.5 V operating range, critical for reliability with variable-battery automotive sensors.
