Nexperia USA Inc. 74HCT3G04DC-Q100H

Overview

74HCT3G04DC-Q100 from Nexperia is an automotive-grade triple inverter logic IC with TTL-compatible inputs, 2.0 V to 6.0 V supply range, -40 °C to +125 °C operating temperature, and VSSOP8 (SOT765-1) package. It provides three independent CMOS inverting buffers used for signal inversion, level translation, and noise filtering in powertrain control modules and body electronics.

For engineers reviewing the 74HCT3G04DC-Q100 datasheet, 74HCT3G04DC-Q100 pinout, 74HCT3G04DC-Q100 application, or 74HCT3G04DC-Q100 equivalent, this device supports high-noise-immunity digital signal conditioning in AEC-Q100 Grade 1 automotive systems where input clamping diodes, low static current (<1 μA), and guaranteed 4.0 mA output drive at 4.5 V are critical selection criteria.

Technical Context

This device implements three independent Schmitt-trigger-free CMOS inverters with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V microcontroller GPIOs without level shifters. Each gate features input clamp diodes allowing safe operation with input voltages exceeding VCC when current-limited.

It operates across a wide voltage range (4.5–5.5 V recommended for TTL compatibility), delivers rail-to-rail output swing (VOH ≥ 4.18 V, VOL ≤ 0.26 V at IO = ±4.0 mA), and maintains propagation delay of 10–29 ns over full temperature range - optimized for deterministic timing in engine control unit (ECU) diagnostic signal paths and sensor interface conditioning.

FAQ

What is the maximum allowable input voltage when VCC = 5.0 V?

The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, but only if input current is limited to ±20 mA via external resistor. This is enabled by internal clamp diodes - confirmed in Table 5 (Limiting Values) and Section 1 General Description. Exceeding this violates Absolute Maximum Ratings and risks permanent damage.

Can this device drive a 50 pF capacitive load at 10 MHz without signal degradation?

Yes: CPD = 9 pF and tpd ≤ 29 ns at 125 °C ensure clean transitions into 50 pF loads at 10 MHz. Dynamic power dissipation remains <1.5 mW (PD = CPD × VCC² × fi × N), and output drive (±4.0 mA) exceeds the 0.31 mA peak current required for 10 MHz square wave into 50 pF - verified in Tables 8 and 11.

Is pin 1 orientation consistent between SOT765-1 (DC) and SOT505-2 (DP) packages?

Yes: both packages locate pin 1 in the lower-left corner beneath the marking code (T04 for this part), with identical pin numbering and function mapping (1A/VCC/3Y/1Y/2A/3A/GND/2Y). Confirmed in Section 6.1 Pinning and Figures 6–7 package outlines.

Does this part support partial power-down operation with unused inputs left floating?

No: all inputs must be actively driven HIGH or LOW. Floating inputs cause increased ICC (up to 410 μA additional per input at VCC = 5.5 V, Table 10) and potential oscillation due to undefined threshold crossing - explicitly warned against in Section 9 Recommended Operating Conditions and Functional Description.
