Nexperia USA Inc. 74AHCT3G04DP,125

Overview

74AHCT3G04DP from Nexperia is a triple CMOS inverter with TTL-compatible input thresholds, designed for 5 V logic translation and signal inversion in mixed-voltage digital systems. It operates from 4.5 V to 5.5 V, features overvoltage-tolerant inputs up to 5.5 V, delivers balanced propagation delays (typ. 3.4 ns at 5 V, CL = 15 pF), and supports industrial temperature range (−40 °C to +125 °C). It is used in bus buffering, level-shifting interfaces, and clock signal conditioning.

For engineers reviewing the 74AHCT3G04DP datasheet, 74AHCT3G04DP pinout, 74AHCT3G04DP application, or 74AHCT3G04DP equivalent, key selection criteria include TTL-level input compatibility, 8-pin TSSOP8 package footprint, guaranteed 8 mA output drive, −40 °C to +125 °C operation, and overvoltage-tolerant inputs enabling safe interfacing with 3.3 V or 5 V sources.

Technical Context

The 74AHCT3G04DP implements three independent inverting buffers with TTL-compatible input switching thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), ensuring reliable recognition of standard 5 V logic levels. Its symmetrical output impedance enables matched rise/fall times and low skew across all three channels.

Designed for mixed-voltage environments, it accepts input voltages up to 5.5 V regardless of supply voltage - a critical feature for translating between 3.3 V controllers and 5 V peripherals. The device meets JESD 78 Class II Level A latch-up immunity (>100 mA) and JEDEC JS-001/JS-002 ESD specifications (HBM >2000 V, CDM >1000 V).

FAQ

Is the 74AHCT3G04DP pin-compatible with the 74AHC3G04DP?

Yes - both share identical TSSOP8 pinout (SOT505-2), same terminal functions, and mechanical footprint. However, the 74AHCT3G04DP uses TTL input thresholds (VIH ≥ 2.0 V), while the 74AHC3G04DP uses CMOS thresholds (VIH ≥ 3.85 V at VCC = 5.5 V), making them electrically non-interchangeable without verifying source logic family compatibility.

Can the 74AHCT3G04DP operate reliably at 4.5 V supply?

Yes - its recommended operating range starts at 4.5 V, and all key parameters (propagation delay, output drive, input thresholds) are fully specified down to this voltage. At 4.5 V, typical propagation delay is 3.7 ns (CL = 15 pF), and VOH remains ≥3.8 V with 8 mA load, ensuring solid noise margin in real-world 5 V rail conditions.

What is the maximum capacitive load the 74AHCT3G04DP can drive while maintaining timing specs?

The device is characterized up to 50 pF load capacitance, with tPD = 7.7 ns (max) and skew ≤0.5 ns across all outputs. Driving >50 pF increases delay nonlinearly and may cause ringing; for loads >50 pF, add series termination (22–33 Ω) near the output and verify signal integrity with oscilloscope measurement at the destination node.

Does the 74AHCT3G04DP require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied HIGH or LOW to prevent floating states that increase ICC and cause erratic output behavior. Due to its TTL-compatible inputs, connecting an unused input directly to VCC (not through a resistor) is preferred; tying to GND is also acceptable. Leaving inputs unconnected violates recommended operating conditions and risks increased power consumption and EMI.
