Product details

Overview

74AUP1G32FZ4-7 from Diodes Incorporated is a single 2-input positive OR gate in X2-DFN1410-6 package, operating from 0.8V to 3.6V supply, delivering ±4mA output drive at 3.0V, with IOFF partial-power-down protection and Schmitt-trigger inputs (250mV hysteresis at 3.0V), deployed in battery-powered portable logic interfaces.

For engineers reviewing the 74AUP1G32FZ4-7 datasheet, 74AUP1G32FZ4-7 pinout, 74AUP1G32FZ4-7 application, or 74AUP1G32FZ4-7 equivalent, key selection criteria include ultra-low static current (<0.9µA), 1.4mm × 1.0mm DFN footprint, propagation delay as low as 1.0ns at 3.3V/5pF, and I_OFF-enabled power-gating capability for multi-rail systems.

Technical Context

This AUP-family CMOS OR gate implements standard Boolean Y = A + B logic with push-pull outputs and full rail-to-rail input tolerance. Its Schmitt-trigger inputs provide 250mV hysteresis at V_CC = 3.0V, enabling robust operation with slow-rising signals in noisy environments.

The IOFF circuit actively disables output leakage when V_CC = 0V, preventing back-current flow during partial power-down-critical for mixed-voltage SoC interconnects. It supports guaranteed operation across –40°C to +125°C ambient with <3.0µA max ICC over full temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - enables direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters
Output Drive	±4mA at 3.0V - sufficient to drive 15pF load with <4.6ns t_PD, supporting high-speed local bus fanout
Static Supply Current	<0.9µA at 25°C - extends battery life in always-on sensor nodes and wearable standby circuits
IOFF Leakage	<0.6µA at 25°C - prevents cross-rail contention when main supply is off while I/O rails remain active
Propagation Delay	1.0ns typical at 3.3V/5pF - meets timing closure for sub-100MHz glue logic in portable applications
Input Hysteresis	250mV at V_CC = 3.0V - rejects noise up to ±125mV on slow-switching control lines (e.g., lid-open sensors)
ESD Rating	2kV HBM, 1kV CDM - exceeds IEC 61000-4-2 Level 2 for handheld device front-end logic

Pinout & Package

X2-DFN1410-6 package: 1.4mm × 1.0mm × 0.4mm body, 0.5mm pad pitch, wettable flank side walls, no leads, thermal pad exposed on bottom (pin 5).

Pin/Terminal	Circuit Role	Design Meaning
1	A Input	First logic input with Schmitt-trigger threshold; accepts 0–V_CC signals regardless of supply voltage
2	B Input	Second logic input with identical Schmitt characteristics; enables OR function with noise immunity
3	GND	Ground reference for all internal circuitry and output stage; must be low-impedance for stable switching
4	Y Output	Push-pull CMOS output capable of sourcing/sinking ±4mA; rail-to-rail swing with <0.1V VOL / >2.7V VOH at 3V
5	V_CC	Power supply input; IOFF activates automatically when V_CC = 0V, disabling Y and isolating A/B from output

Key Features

Feature	Design Value
Ultra-low static power	ICC < 0.9µA ensures negligible battery drain in always-on wake-up logic paths
IOFF partial-power-down	Prevents damaging back-current when V_CC is off but A/B or Y are biased by other powered rails
Schmitt-trigger inputs	250mV hysteresis eliminates chatter on mechanical switch inputs or slow RC-debounced signals
Wide V_CC range	0.8V–3.6V operation supports direct connection to modern low-voltage microcontrollers and PMIC outputs
Lead-free & green compliance	Fully RoHS-compliant, halogen- and antimony-free construction per JEDEC J-STD-020 moisture sensitivity level 1

Applications

Smartphone Power Sequencing

Wearable Sensor Hub Logic

Use Scenario: OR-ing reset signals from multiple subsystems (PMIC, baseband, application processor) to generate a unified system reset pulse.

IC Role / Device Role / Timing Role: Single-gate combinatorial logic element performing asynchronous signal aggregation with sub-5ns propagation delay.

Use Value: Eliminates need for discrete diode-OR networks, reducing board area by 60% and improving reset timing margin by removing diode forward-voltage uncertainty.

Use Scenario: Debouncing and combining interrupt outputs from accelerometer, gyroscope, and ambient light sensor before routing to MCU GPIO.

IC Role / Device Role / Timing Role: Noise-immune logic gate accepting slow-rising sensor interrupts and delivering clean, fast-rising MCU-compatible edges.

Use Value: Schmitt-trigger inputs reject EMI-induced glitches on flex-cable sensor traces, reducing false wake-ups by >95% versus standard CMOS inputs.

USB-C Port Controller Interface

IoT Edge Node Status Aggregation

Use Scenario: Merging VBUS presence detection and CC line state signals to assert "port ready" status to USB controller firmware.

IC Role / Device Role / Timing Role: Low-voltage logic gate interfacing between 3.3V port controller and 1.8V microcontroller I/O pins.

Use Value: 0.8V–3.6V supply range allows direct operation from same LDO powering the MCU, avoiding extra level-shifter IC and BOM cost.

Use Scenario: Combining fault flags from battery monitor, temperature sensor, and cellular modem into a single hardware alert line for watchdog monitoring.

IC Role / Device Role / Timing Role: Fail-safe combinatorial element ensuring any asserted fault triggers immediate system shutdown regardless of clock domain.

Use Value: IOFF isolation guarantees no leakage path from powered fault lines into unpowered safety controller domain during brown-out conditions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G32DBVR	Higher ICC (1µA typ), no Schmitt inputs, 1.65–5.5V supply range	Lacks noise immunity on slow inputs; requires external filtering for mechanical switches	Select when higher V_CC (>3.6V) or legacy 5V compatibility is required
NC7SZ32P5X	Lower drive (±2.6mA at 3.3V), no IOFF, SOT-353 package (2.0×2.0mm)	Cannot support partial-power-down architectures; larger footprint increases PCB area by 2.8×	Select when cost-sensitive designs prioritize lowest unit price over space and power optimization

Compared with SN74LVC1G32DBVR and NC7SZ32P5X, the 74AUP1G32FZ4-7 uniquely delivers simultaneous ultra-low ICC, Schmitt-trigger noise rejection, and IOFF-enabled power-domain isolation in the smallest DFN footprint-making it optimal for space-constrained, battery-operated systems requiring robust signal integrity.

FAQ

What is the maximum recommended operating temperature for continuous use?

The 74AUP1G32FZ4-7 is rated for continuous operation from –40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C; with θ_JA = 460°C/W in X2-DFN1410-6, power dissipation should remain below 43mW at +125°C ambient to maintain safe thermal margin.

Does this device require external pull-up or pull-down resistors on unused inputs?

No. Per datasheet Note 8, unused inputs must be tied directly to V_CC or GND-not through resistors-to ensure defined logic state and prevent increased ICC or oscillation. Floating inputs are strictly prohibited due to CMOS input structure and potential shoot-through current.

Can the 74AUP1G32FZ4-7 drive a 50pF capacitive load reliably?

At 3.3V supply, the device drives 30pF with t_PD ≤ 8.5ns (max) and VOL ≤ 0.45V. For 50pF, propagation delay increases beyond datasheet characterization limits; design validation is required. Use series termination or reduce trace length to limit effective load capacitance to ≤30pF for guaranteed timing compliance.

Is the thermal pad on the X2-DFN1410-6 package electrically connected internally?

No-the exposed thermal pad (pin 5) is electrically isolated and intended solely for thermal conduction. It must be soldered to a PCB thermal plane using a solid copper pour, but must not be connected to any signal or power net to avoid short circuits or EMI coupling into the ground plane.
