Diodes Incorporated 74AUP1G06FX4-7

Overview

74AUP1G06FX4-7 from Diodes Incorporated is a single CMOS inverter with open-drain output, designed for ultra-low-power portable systems operating from 0.8V to 3.6V. It delivers ±4mA drive at 3.0V, features IOFF partial power-down protection, and integrates Schmitt-trigger inputs with ~250mV hysteresis at 3.0V for robust noise immunity in battery-powered interfaces.

For engineers reviewing the 74AUP1G06FX4-7 datasheet, 74AUP1G06FX4-7 pinout, 74AUP1G06FX4-7 application, or 74AUP1G06FX4-7 equivalent, this device is selected for level-shifting, I²C bus pull-up control, and low-voltage logic inversion where static current <0.9µA and propagation delay as low as 0.8ns (at 3.3V, CL=5pF) are critical.

Technical Context

This AUP-family inverter implements a single positive-logic inversion function (Y = A̅) with open-drain output, requiring an external pull-up resistor for high-level assertion. Its IOFF circuit actively disables output leakage during partial power-down, preventing backflow when VCC is inactive while other system rails remain live.

Schmitt-trigger input thresholds scale with VCC (e.g., VIH = 0.80×VCC at 0.8–1.65V), enabling reliable operation across wide supply ranges and tolerance to slow-rising signals. Propagation delay varies from 0.8ns to 27.8ns depending on VCC and load capacitance (5–30pF), with typical Cpd = 4.2pF at 3.3V.

FAQ

What is the maximum capacitive load the 74AUP1G06FX4-7 can drive reliably?

The device is characterized up to 30pF load capacitance, with propagation delay increasing from 0.8ns (5pF) to 11.9ns (30pF) at 3.3V. For reliable timing closure beyond 30pF, add series resistance to limit slew rate and prevent ringing; the open-drain output requires external pull-up selection based on target rise time and bus voltage.

Can the 74AUP1G06FX4-7 be used without a pull-up resistor?

No - the open-drain output cannot source current, so a pull-up resistor is mandatory to establish a valid HIGH logic level. Typical values range from 2.2kΩ (for fast rise time on 3.3V buses) to 10kΩ (for ultra-low I²C standby current); value selection depends on bus capacitance, speed, and power budget.

Does the NC pin require PCB routing or thermal treatment?

No - pins 4 and 6 are internally unconnected and must remain floating. Do not connect them to GND, VCC, or traces; avoid solder mask openings or thermal reliefs. This prevents unintended coupling or parasitic capacitance that could affect high-frequency performance.

How does IOFF behave when VCC is disconnected but input voltage remains present?

When VCC = 0V, the IOFF circuit disables the output regardless of input state, limiting leakage to ±0.2µA max. However, input voltage must stay within -0.5V to +4.6V absolute maximum ratings - applying voltage to A while VCC is absent risks exceeding clamp current limits unless current is externally limited to ≤50mA.
