Nexperia USA Inc. 74HCT3G04DP-Q100H

Overview

74HCT3G04DP-Q100 from Nexperia is an automotive-grade triple inverter IC with TTL-compatible inputs, 2.0 V to 6.0 V supply range, -40 °C to +125 °C operating temperature, and TSSOP8 (SOT505-2) package. It provides three independent logic inversion functions with high noise immunity and input clamp diodes enabling overvoltage-tolerant interfacing-used in body control modules for signal conditioning of switch inputs.

For engineers reviewing the 74HCT3G04DP-Q100 datasheet, 74HCT3G04DP-Q100 pinout, 74HCT3G04DP-Q100 application, or 74HCT3G04DP-Q100 equivalent, key selection criteria include TTL-level input compatibility, AEC-Q100 Grade 1 qualification, propagation delay at 4.5 V (10–29 ns), output drive capability (±4 mA), and TSSOP8 thermal derating behavior above 96 °C.

Technical Context

This device implements three independent CMOS-based inverting buffers using standard TTL input threshold levels (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), ensuring interoperability with legacy 5 V logic families. Each gate features input clamp diodes for current-limited overvoltage tolerance up to VCC + 0.5 V.

It operates across a wide supply range (4.5–5.5 V nominal), delivers rail-to-rail output swing under load (VOH ≥ 4.18 V, VOL ≤ 0.26 V at IO = ±4 mA), and maintains specified timing performance over full automotive temperature range (-40 °C to +125 °C) per AEC-Q100 stress test requirements.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple inverter applications.

Compared with 74HCT3G04DC-Q100, the DP variant offers superior thermal performance in sustained +125 °C environments due to larger TSSOP8 pad area; versus SN74LVC3G04-Q1, it retains 5 V system compatibility and pinout consistency but trades off speed for broader supply and temperature coverage.

FAQ

Is 74HCT3G04DP-Q100 pin-compatible with 74HC3G04DP-Q100?

Yes - both share identical TSSOP8 (SOT505-2) pinout and physical footprint. The key difference is input threshold: 74HCT3G04DP-Q100 uses TTL-compatible inputs (VIH ≥ 2.0 V), while 74HC3G04DP-Q100 requires CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V). Swapping requires verifying source logic family compatibility.

What is the maximum recommended continuous output current per inverter stage?

The absolute maximum output current is ±25 mA per output (Table 5), but the recommended operating condition specifies ±4.0 mA at VCC = 4.5 V for VOH/VOL compliance. Sustained operation above ±4 mA risks exceeding VOL/VOH limits and increasing dynamic power beyond 250 mW total package limit.

Does this device support mixed-voltage interfacing, e.g., 3.3 V inputs driving a 5 V supply?

No - inputs are referenced to VCC. Applying 3.3 V to an input while VCC = 5 V violates the VI < VCC + 0.5 V limiting value only if exceeding 5.5 V; however, 3.3 V falls within valid VI range (0–VCC) and meets VIH minimum (2.0 V) for TTL compatibility. No level shifter is needed.

How does the input clamp diode affect external resistor selection for overvoltage protection?

When interfacing to voltages > VCC, a series current-limiting resistor must restrict I_IK to ≤ ±20 mA (Table 5). For example, with V_IN = 12 V and VCC = 5 V, R ≥ (12 V − 5.5 V) / 20 mA = 325 Ω. Lower resistance increases stress on the clamp diode and may exceed its safe operating area.
