STMicroelectronics 74AUP1G04GTR

Overview

74AUP1G04GTR from STMicroelectronics is a low-power CMOS single inverter gate operating from 1.2 V to 3.6 V, delivering 4.3 ns max propagation delay at 2.3 V, 1 µA max quiescent current at 85 °C, and ESD protection up to 2000-V HBM. It serves as a logic-level signal inverter in battery-powered portable electronics requiring ultra-low static power and rail-to-rail input compatibility.

For engineers reviewing the 74AUP1G04GTR datasheet, 74AUP1G04GTR pinout, 74AUP1G04GTR application, or 74AUP1G04GTR equivalent, this device is selected for low-voltage logic translation, power-gating control, and noise-immune signal conditioning in space-constrained mobile interfaces where supply voltage flexibility and sub-1 µA standby current are critical.

Technical Context

The 74AUP1G04GTR implements a single unbuffered inverting gate using C2MOS technology with balanced tPLH/tPHL delays and input/output overvoltage tolerance beyond VCC. Its inputs accept voltages up to 4.6 V regardless of VCC, enabling safe interfacing with higher-voltage logic domains.

It features power-down protection on all I/O pins, ensuring high-impedance behavior during VCC = 0 V operation, and includes integrated ESD structures meeting 2000-V HBM, 200-V MM, and 1000-V CDM standards - critical for handheld assembly and field reliability.

FAQ

Can 74AUP1G04GTR operate reliably at 1.2 V supply?

Yes. The device is fully specified down to 1.2 V, with guaranteed VOH ≥ VCC – 0.2 V and VOL ≤ 0.25 V at 1 mA load. Propagation delay increases to 13.3 ns (max) at 1.2 V/15 pF, but logic functionality remains intact across the full –40 °C to +85 °C range.

Is the NC pin on SOT-665 electrically isolated?

Yes. Pin 1 is a true no-connect terminal with no internal silicon connection. It must be left floating or grounded per PCB layout best practices - neither soldering nor routing to any net is required or recommended, as it serves only as a mechanical alignment aid.

Does 74AUP1G04GTR support hot insertion when VCC = 0 V?

Yes. Input and output pins feature power-down protection circuitry that forces high-impedance states when VCC is absent. This prevents back-powering of the supply rail and avoids contention with other live circuits during hot-plug events in modular accessories.

What is the maximum capacitive load this inverter can drive?

The device is characterized up to 30 pF load capacitance in AC testing, with tPD degradation limited to 16 ns (max) at 1.2 V. For reliable operation beyond 30 pF, add a series resistor (22–47 Ω) near the output to damp ringing and limit peak current, especially when driving long traces or multiple parallel inputs.
