Nexperia USA Inc. 74AHCT3G04DP-Q100H

Overview

74AHCT3G04DP-Q100 from Nexperia is a triple CMOS inverter IC with TTL-compatible input thresholds, rated for automotive Grade 1 (-40 °C to +125 °C), featuring overvoltage-tolerant inputs up to 5.5 V, 8-pin TSSOP8 package (SOT505-2), and propagation delay of 3.4–8.5 ns at V_CC = 4.5–5.5 V. It serves as a level-shifting logic buffer in automotive body control modules requiring robust noise immunity and mixed-voltage signal inversion.

For engineers reviewing the 74AHCT3G04DP-Q100 datasheet, 74AHCT3G04DP-Q100 pinout, 74AHCT3G04DP-Q100 application, or 74AHCT3G04DP-Q100 equivalent, key selection criteria include its AEC-Q100 qualification, TTL input compatibility, 8 mA output drive capability, symmetrical output impedance, and operation across 4.5–5.5 V supply rails in harsh-temperature environments.

Technical Context

This device implements three independent inverting buffers with Schmitt-trigger-free CMOS topology and TTL-level input switching thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V at V_CC = 4.5–5.5 V). Each gate delivers rail-to-rail output swing with matched high/low drive strength (I_OH/I_OL = ±8 mA) and exhibits balanced t_PLH/t_PHL propagation delays.

Its overvoltage-tolerant inputs accept signals up to 5.5 V regardless of V_CC, enabling safe interfacing between 3.3 V controllers and 5 V legacy subsystems. The design incorporates JESD78 Class II Level A latch-up immunity (>100 mA) and dual ESD protection (HBM >2000 V, CDM >1000 V).

FAQ

What is the maximum input voltage the 74AHCT3G04DP-Q100 can tolerate?

The 74AHCT3G04DP-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of V_CC level, as confirmed in Section 6.2 and Table 5 of the datasheet. This allows safe connection to 5 V buses even when powered from a lower supply, eliminating risk of damage during hot-swap or power sequencing events.

Does this part support operation at 3.3 V supply?

No-this AHCT variant is specified only for 4.5 V to 5.5 V supply operation, per Table 6. Attempting to operate below 4.5 V risks unreliable switching due to insufficient noise margin and undefined output behavior. For 3.3 V systems, consider the pin-compatible 74AHC3G04DP-Q100 instead.

How many inverters are integrated in this single package?

The 74AHCT3G04DP-Q100 integrates exactly three independent inverting buffers in one TSSOP8 package, as stated in the General Description and confirmed by the functional diagram (Fig. 3) and pin description table. Each inverter has dedicated input (1A/2A/3A) and output (1Y/2Y/3Y) terminals with no shared internal nodes.

Is the TSSOP8 package RoHS and REACH compliant?

Yes-the SOT505-2 package used for 74AHCT3G04DP-Q100 is fully RoHS-compliant (lead-free termination, homogeneous material restrictions met) and REACH-conformant, as documented in Nexperia's official product compliance statements and material declarations available on their website.
