Product details

Overview

74AUP1G09SE-7 from Diodes Incorporated is a single 2-input positive AND gate with open-drain output, designed for ultra-low-power logic interfacing in battery-powered systems. It operates across 0.8V–3.6V supply, delivers 4mA output drive at 3.0V, features IOFF partial power-down protection, and includes Schmitt-trigger inputs with ~250mV hysteresis at 3.0V for noise immunity in noisy environments.

For engineers reviewing the 74AUP1G09SE-7 datasheet, 74AUP1G09SE-7 pinout, 74AUP1G09SE-7 application, or 74AUP1G09SE-7 equivalent, key selection criteria include open-drain compatibility with I²C/1-wire buses, sub-1µA static current, wide VCC range for multi-rail voltage translation, and validated IOFF behavior during system sleep states.

Technical Context

This AUP-family device implements standard Boolean AND logic (Y = A • B) with an open-drain output requiring an external pull-up resistor. Its IOFF circuit actively disables output leakage when VCC = 0V, preventing back-current flow into powered-down subsystems - critical for mixed-voltage domain isolation.

Schmitt-trigger inputs provide robust switching with defined hysteresis (~250mV at VCC = 3.0V), enabling reliable operation with slow-rising signals (e.g., RC-filtered reset lines or mechanical switch debouncing). Propagation delay ranges from 0.9ns (typ, 3.3V, CL = 5pF) to 27ns (0.8V, CL = 30pF), scaling predictably with supply and load.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	0.8V to 3.6V - supports direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters.
Output Type	Open-drain - enables wired-AND bus topology, I²C-compatible signaling, and flexible pull-up voltage selection (up to 5.5V).
I_OL Drive	4mA at V_CC = 3.0V - sufficient to sink standard I²C bus capacitance (400pF) at 100kHz with <1V drop.
I_CC Static Current	<0.9µA max at +25°C - extends battery life in always-on sensor nodes and wearable standby modes.
IOFF Leakage	±0.5µA max (V_I/V_O = 0–3.6V) - prevents >1µA backfeed current when host MCU is powered down.
Input Hysteresis	~250mV at V_CC = 3.0V - rejects noise spikes up to ±125mV on slow edges (e.g., thermistor-based wake-up signals).
t_PD Delay	0.9ns typ (3.3V, CL = 5pF) - meets timing budgets for low-latency enable/control paths in portable audio codecs.

Pinout & Package

SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm pitch) - compact leaded package with exposed pad option for thermal relief in space-constrained PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 (A)	Data Input	Primary logic input; Schmitt-triggered for noise immunity; VIH/VIL thresholds scale with VCC.
2 (B)	Data Input	Secondary logic input; identical electrical specs to Pin 1; both inputs tolerate 0–3.6V regardless of VCC.
3 (GND)	Ground Reference	Return path for all internal logic and output current; must be low-impedance to maintain noise margin.
4 (Y)	Open-Drain Output	Active-low sinking node; requires external pull-up; supports voltage translation up to 5.5V on Y line.
5 (V_CC)	Power Supply	Core logic supply; IOFF activates when V_CC = 0V, disabling Y regardless of A/B state.

Key Features

Feature	Design Value
Ultra-low static power	ICC < 0.9µA ensures < 3µA total quiescent draw in 3-gate control chains for medical patch sensors.
IOFF partial power-down	Blocks >99% of back-current flow when VCC is removed - essential for hot-swap USB-C accessory detection.
Schmitt-trigger inputs	250mV hysteresis at 3.0V eliminates chatter on mechanical switch inputs without external RC filtering.
ESD robustness	2kV HBM / 1kV CDM rating allows direct handling in bench assembly without special ESD controls.
Wide VCC range	0.8–3.6V operation enables single BOM reuse across 1.2V SoC rails and 3.3V peripheral interfaces.

Applications

Use Scenario: Coordinating power-up order of AP, PMIC, and display driver ICs in smartphones using discrete enable signals.

IC Role / Device Role / Timing Role: AND gate combines two independent reset sources to generate synchronized enable pulse for display power rail.

Use Value: Open-drain output allows shared pull-up to 3.3V while inputs accept 1.2V AP GPIOs - eliminating discrete level shifters.

Use Scenario: Interfacing 1.8V microcontroller I²C pins to 3.3V sensor EEPROM on same bus segment.

IC Role / Device Role / Timing Role: Wired-AND logic element implementing bidirectional data arbitration with external 3.3V pull-ups.

IC Role / Device Role / Timing Role: Dual-input AND gate with Schmitt-trigger inputs conditioning noisy tactile switch signals.

Use Value: 250mV hysteresis rejects bounce transients <1ms duration; 0.9µA ICC extends coin-cell life beyond 2 years.

Use Scenario: Generating clean interrupt signal from unfiltered push-button input in programmable logic controllers.

Use Value: Open-drain output interfaces directly to 5V-tolerant FPGA input; IOFF isolates button circuit during PLC firmware update.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G08DSFR	Pure CMOS push-pull output; no IOFF; 1.65–5.5V supply range.	Requires external isolation for partial power-down; unsuitable for mixed-voltage bus arbitration.	Select when driving high-speed loads (>50MHz) where open-drain delay is unacceptable.
NC7SZ08P5X	Push-pull output; lower ICC (0.1µA); no Schmitt inputs; 1.65–5.5V operation.	Lacks noise immunity on slow edges; cannot replace 74AUP1G09SE-7 in RC-debounced switch circuits.	Prefer for cost-sensitive consumer audio docks where input slew rates exceed 1V/ns.

Compared with SN74LVC1G08DSFR and NC7SZ08P5X, the 74AUP1G09SE-7 uniquely combines open-drain flexibility, sub-1µA quiescent current, and Schmitt-trigger noise rejection - making it irreplaceable in battery-critical, multi-rail, and noisy-switch applications.

FAQ

Can 74AUP1G09SE-7 drive a 10kΩ pull-up to 5V?

Yes. The open-drain output is rated for 4mA sink current at 3.0V, allowing safe operation with a 10kΩ pull-up to 5V (I = 500µA). Output voltage drop remains below 0.45V per datasheet, ensuring valid logic-low levels for 5V-tolerant receivers.

Does IOFF function when only one supply rail is active?

Yes. IOFF activates whenever VCC = 0V, regardless of input or output voltage. If VCC is disconnected while A/B/Y are biased to 3.3V, the output is electrically isolated - preventing >0.5µA back-current into the powered-down domain.

What is the maximum capacitive load for guaranteed timing performance?

The datasheet specifies switching characteristics up to 30pF. At 3.3V, tPD increases from 0.9ns (5pF) to 2.3ns (30pF). For loads >30pF, propagation delay rises nonlinearly; use a buffer stage if driving >50pF traces or multiple inputs.

Is the Schmitt-trigger hysteresis voltage fixed or supply-dependent?

Hysteresis is supply-dependent: ~250mV at VCC = 3.0V, scaling approximately linearly. At 1.2V, hysteresis drops to ~100mV. This maintains consistent noise margin percentage (±4–5% of VCC) across the full 0.8–3.6V operating range.
