Nexperia USA Inc. 74HC3G04DC,125

Overview

74HC3G04DC,125 from Nexperia is a triple CMOS inverter IC in VSSOP8 package, operating from 2.0 V to 6.0 V supply, delivering propagation delays as low as 6 ns at 6.0 V and supporting industrial temperature range (–40 °C to +125 °C). It features input clamp diodes enabling safe interfacing with voltages exceeding VCC using current-limiting resistors, and exhibits high noise immunity with ±20 mA clamping current capability.

For engineers reviewing the 74HC3G04DC,125 datasheet, 74HC3G04DC,125 pinout, 74HC3G04DC,125 application, or 74HC3G04DC,125 equivalent, this device is selected for logic-level inversion in space-constrained digital subsystems requiring low-power, rail-to-rail compatible signal conditioning - especially where mixed-voltage domain interfacing and ESD-hardened inputs are critical.

Technical Context

This device implements three independent, unbuffered CMOS inverter gates in a single monolithic die. Each gate follows standard TTL-compatible logic behavior (L→H, H→L) with no internal hysteresis or Schmitt-trigger action. Input clamp diodes are integrated per pin to support overvoltage tolerance when used with external series resistors.

It operates across two logic families: 74HC3G04 uses CMOS-level inputs (VIH ≥ 70% VCC), while the pin-identical 74HCT3G04 variant accepts TTL-level inputs (VIH = 2.0 V min). Both share identical output drive strength (±4.0 mA at VCC = 4.5 V) and thermal derating profiles (4.9 mW/K above 99 °C).

FAQ

What is the maximum allowable input voltage when VCC = 3.3 V?

The absolute maximum input voltage is VCC + 0.5 V = 3.8 V, enabled by integrated clamp diodes. Exceeding this requires external current limiting to keep IIK ≤ ±20 mA. Inputs may be driven from 5 V logic only when series resistors limit current to ≤20 mA - e.g., ≥150 Ω for 5 V → 3.3 V translation.

Can 74HC3G04DC,125 drive a 50 pF capacitive load at 10 MHz?

Yes: with CPD = 9 pF and typical tpd = 8 ns at VCC = 4.5 V, dynamic power is PD ≈ 9 × (4.5)² × 10 × 3 = ~5.4 mW - well within the 250 mW thermal limit. Rise/fall times remain <15 ns, ensuring clean edges into 50 pF loads without excessive ringing.

Is this device suitable for automotive applications?

No - it is not AEC-Q100 qualified. While rated for –40 °C to +125 °C, Nexperia explicitly states non-automotive qualification in its legal disclaimers. For automotive use, select the pin-compatible 74HC3G04-Q100 variant, which undergoes additional stress testing and PPAP documentation.

How does the 74HC3G04 differ from the 74HCT3G04 in practical design?

The 74HC3G04 accepts CMOS-level inputs (VIH ≥ 0.7×VCC), while 74HCT3G04 accepts TTL-level inputs (VIH ≥ 2.0 V at VCC = 4.5–5.5 V). This makes the HCT version compatible with legacy 5 V TTL outputs without pull-ups; the HC version requires proper VCC scaling for reliable VIH detection in mixed-voltage systems.
