Product details

Overview

74AUP1G08FX4-7 from Diodes Incorporated is a single 2-input positive AND gate in ultra-low-power CMOS logic, designed for battery-powered portable systems. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and integrates Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V-enabling robust signal conditioning in noise-prone mobile interfaces.

For engineers reviewing the 74AUP1G08FX4-7 datasheet, 74AUP1G08FX4-7 pinout, 74AUP1G08FX4-7 application, or 74AUP1G08FX4-7 equivalent, this device is selected for low-voltage logic level translation, enable/control gating in wearables and IoT sensors, and power-aware signal routing where static current <0.9µA and propagation delay ≤4.8ns (at 3.3V, CL=10pF) are critical.

Technical Context

This AUP-family AND gate implements standard Boolean Y = A • B using advanced ultra-low-power CMOS process technology. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, supporting mixed-voltage system partitioning and hot-swap readiness.

Schmitt-trigger inputs provide input hysteresis (~250mV at 3.0V), allowing reliable operation with slow-rising/falling signals from mechanical switches, analog comparators, or legacy microcontroller GPIOs-without external RC filtering.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - supports direct interfacing with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters.
Max Output Drive	±4mA at VCC = 3.0V - sufficient to drive multiple 74AUP inputs or small capacitive loads (<15pF) with controlled edge rates.
Static Supply Current	<0.9µA - enables multi-year battery life in always-on sensor nodes and real-time clock gating circuits.
Propagation Delay	4.8ns max (3.3V, CL = 10pF) - ensures timing-critical control path integrity in high-speed enable/disable sequencing.
IOFF Leakage	≤0.6µA at VCC = 0V - guarantees safe isolation of powered-down subsystems in modular power architectures.
Input Hysteresis	~250mV at VCC = 3.0V - rejects up to ±125mV of noise on A/B inputs, eliminating false triggering from EMI or crosstalk.
ESD Protection	2kV HBM, >1kV CDM - meets IEC 61000-4-2 Level 2 requirements for handheld and wearable end-equipment.

Pinout & Package

X2-DFN1409-6 chip-scale package: 1.4mm × 0.9mm × 0.4mm, 0.5mm pad pitch, bottom-side thermal pad (non-electrical), leadless and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1 (A)	Data Input	Primary logic input with Schmitt-trigger threshold; must be tied to VCC or GND if unused per datasheet Note 8.
2 (B)	Data Input	Secondary logic input with identical Schmitt characteristics; enables dual-signal gating (e.g., wake-up + valid).
3 (GND)	Ground Reference	Low-impedance return path for all internal logic and output current; requires solid PCB ground plane connection.
4 (Y)	Data Output	Push-pull CMOS output capable of sourcing/sinking ±4mA; compatible with 1.8V/2.5V/3.3V logic families.
5 (VCC)	Power Supply	Single-supply rail for entire gate; supports dynamic voltage scaling down to 0.8V for ultra-low-energy operation.
6 (NC)	No Connect	Internally unconnected die pad; must remain floating or grounded per layout guidelines-no electrical function.

Key Features

Feature	Design Value
Ultra-low static power	I_CC < 0.9µA enables multi-year operation from coin-cell batteries in maintenance-free IoT endpoints.
IOFF partial power-down	Active output disable at VCC = 0V prevents back-current into powered sections-critical for USB-C detachable modules.
Schmitt-trigger inputs	250mV hysteresis at 3.0V eliminates need for external debouncing components in pushbutton or switch interface designs.
Wide VCC range	0.8V–3.6V operation allows direct use with energy-harvesting PMIC outputs and multi-rail SoC power domains.
Lead-free & green compliance	Fully RoHS 3, halogen- and antimony-free (Br+Cl <1500ppm, Sb <1000ppm) - satisfies automotive and medical regulatory mandates.

Applications

Wearable Sensor Hub Control

USB-C Port Power Enable Logic

Use Scenario: Enabling/disabling accelerometer and gyroscope power rails based on motion detection and host presence signals.

IC Role / Device Role / Timing Role: Dual-input AND gate synchronizing motion interrupt (A) and USB enumeration status (B) to assert sensor VDD_EN (Y).

Use Value: Eliminates external pull-ups and reduces BOM count by integrating Schmitt inputs-improving noise immunity on flex-cable routed interrupt lines.

Use Scenario: Controlling VBUS power delivery to downstream peripherals only when both CC line handshake and system policy permit.

IC Role / Device Role / Timing Role: Logic-level gating of policy decision (A) and CC-detected partner capability (B) to drive load-switch EN pin (Y).

Use Value: IOFF functionality isolates the gate during system suspend, preventing leakage through the load switch control path and extending standby time.

Low-Power Display Backlight Sequencing

Industrial Edge Node Wake-Up Arbiter

Use Scenario: Coordinating display enable and brightness PWM signals to avoid visual artifacts during cold start.

IC Role / Device Role / Timing Role: AND-ing MCU display-enable (A) and stable DC-DC output OK (B) to generate clean backlight enable (Y).

Use Value: 0.8V minimum VCC allows direct use with buck converter feedback rails-removing need for auxiliary LDO.

Use Scenario: Combining PIR sensor trigger and LoRaWAN network availability before waking main MCU from deep sleep.

IC Role / Device Role / Timing Role: Gating wake-source (A) and radio-ready flag (B) to generate synchronized wake pulse (Y) to RTC interrupt input.

Use Value: Sub-1µA ICC ensures negligible impact on 10-year battery budget; Schmitt inputs tolerate slow-rising PIR output edges.

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
SN74LVC1G08DBVR	Higher ICC (1µA typ), wider VCC (1.65–5.5V), no IOFF or Schmitt inputs	Requires external pull-ups for open-drain sources; unsuitable for partial power-down systems	Select when interfacing with 5V-tolerant logic or needing higher drive strength (±32mA), but not for ultra-low-power or hot-swap isolation.
74AHC1G08SE-7	Higher speed (2.5ns typ @ 3.3V), no Schmitt inputs, IOFF not supported, VCC min = 2.0V	Cannot accept sub-2.0V inputs; lacks noise immunity for mechanical switch interfaces	Prefer for high-frequency clock gating where input slew rate is controlled and full-system power cycling is used instead of partial shutdown.

Compared with SN74LVC1G08DBVR and 74AHC1G08SE-7, the 74AUP1G08FX4-7 uniquely combines sub-1µA static current, 0.8V operation, IOFF, and Schmitt inputs-making it the only choice for battery-constrained, mixed-voltage, noise-prone embedded control paths requiring guaranteed signal integrity and zero-backflow safety.

FAQ

What is the maximum recommended load capacitance for reliable 74AUP1G08FX4-7 operation?

The device is characterized up to 30pF load capacitance, with propagation delay increasing predictably (e.g., 6.5ns max at 3.3V, CL=30pF). For stable operation beyond 30pF, add series resistance to limit slew rate and prevent ringing-verified in Diodes' application note AP02012 for DFN-packaged AUP devices.

Can Pin 6 (NC) be connected to ground or left floating in PCB layout?

Pin 6 is a no-connect terminal with no internal bond wire; Diodes' package outline documentation specifies it must remain electrically floating. Grounding it may cause unintended thermal or mechanical stress on the die attach-follow X2-DFN1409-6 pad layout guide (AP02007) for correct land pattern.

Does the 74AUP1G08FX4-7 support true bidirectional signal flow?

No-it is a unidirectional AND gate with defined inputs (A, B) and output (Y). The IOFF feature only disables output drive during power-down; it does not enable reverse signal transmission. Bidirectional data paths require dedicated bus switches or transceivers, not logic gates.

How does the Schmitt-trigger input affect timing analysis in synchronous designs?

Schmitt action adds deterministic hysteresis but does not alter propagation delay specifications-the t_pd values in the datasheet already include input threshold crossing effects. Timing margins should use the published max t_pd (e.g., 4.8ns at 3.3V), as hysteresis improves noise rejection without degrading worst-case delay.
