Nexperia USA Inc. 74AUP3G3404DCH

Overview

74AUP3G3404 from Nexperia is a low-power triple-gate logic device integrating two non-inverting buffers (1A→1Y, 2A→2Y) and one inverting buffer (3A→3Y), with Schmitt-trigger inputs enabling robust noise immunity across 0.8 V–3.6 V supply operation. It delivers ICC ≤ 0.9 μA max static current, tPD as low as 1.1 ns at 3.6 V/5 pF, and IOFF-enabled partial power-down protection for system-level power sequencing in portable and battery-powered interfaces.

For engineers reviewing the 74AUP3G3404 datasheet, 74AUP3G3404 pinout, 74AUP3G3404 application, or 74AUP3G3404 equivalent, this device supports voltage-level translation, signal conditioning, and noise-tolerant input buffering in space-constrained, ultra-low-power embedded control and sensor interface circuits where supply rail flexibility and I/O isolation during power-down are critical.

Technical Context

This device implements three independent logic gates in a single 8-pin package: two true buffers (1Y = 1A, 2Y = 2A) and one inverter (3Y = NOT 3A), each with Schmitt-trigger inputs ensuring hysteresis of ≥0.1VCC across the full 0.8–3.6 V VCC range. Input thresholds scale dynamically with VCC, supporting interoperability between mixed-voltage domains without external biasing.

The IOFF circuit actively disables all outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max and enabling hot-swap compatibility and safe multi-rail power sequencing. All inputs tolerate up to 3.6 V regardless of VCC, allowing direct connection to higher-voltage logic without level shifters.

FAQ

Does the 74AUP3G3404 support level-shifting between different VCC domains?

No - it does not perform bidirectional level shifting. However, its inputs tolerate up to 3.6 V regardless of VCC (e.g., 1.8 V supply with 3.3 V input), enabling unidirectional interface to higher-voltage peripherals without external components. Output swing remains rail-to-rail relative to its own VCC.

What is the maximum capacitive load the 74AUP3G3404 can drive while maintaining specified tPD?

The datasheet specifies tPD up to 30 pF load capacitance across all VCC ranges. At VCC = 3.6 V, tPD remains ≤ 7.2 ns with 30 pF load. For loads >30 pF, propagation delay increases linearly; design margin requires derating based on actual CL and VCC per Table 9.

Can the 74AUP3G3404 be used with VCC = 0 V while other system rails remain active?

Yes - the IOFF circuit activates automatically when VCC = 0 V, disabling all outputs and limiting leakage to ±0.75 μA max. This safely isolates the device from live inputs/outputs during partial power-down, preventing back-current damage to upstream drivers or downstream receivers.

How does the Schmitt-trigger input improve performance in noisy environments?

Schmitt-trigger inputs provide hysteresis ≥0.1VCC, meaning VIH and VIL differ by at least 100 mV at 1.0 V supply. This prevents multiple transitions on slowly rising/falling signals (e.g., mechanical switches, thermistor dividers) and rejects high-frequency noise spikes below the hysteresis threshold without external filtering.
