Diodes Incorporated 74AUP2G3404FW4-7

Overview

74AUP2G3404FW4-7 from Diodes Incorporated is a dual-gate Advanced Ultra Low Power (AUP) CMOS logic device containing one non-inverting buffer and one inverting gate, both with push-pull outputs. It operates across 0.8V–3.6V supply voltage, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and supports battery-powered portable electronics including tablets and GPS devices.

For engineers reviewing the 74AUP2G3404FW4-7 datasheet, 74AUP2G3404FW4-7 pinout, 74AUP2G3404FW4-7 application, or 74AUP2G3404FW4-7 equivalent, key selection criteria include its ultra-low ICC (<0.9µA), Schmitt-trigger inputs (250mV hysteresis at 3.0V), 6pF typical dynamic capacitance, and DFN1010-6 package compatibility with space-constrained PCB layouts.

Technical Context

This dual-function logic gate integrates independent buffer and inverter paths sharing a common VCC and GND, enabling signal conditioning and polarity inversion within a single ultra-small footprint. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow, satisfying IEC 61000-4-2 ESD robustness requirements (2kV HBM, 1kV CDM).

The Schmitt-trigger inputs provide noise immunity for slow-rising/falling signals-critical in low-power sensor interfaces and wake-up circuits-while the 3.2ns typical propagation delay at 3.3V/CL=5pF ensures timing integrity in high-speed data paths without compromising energy efficiency.

FAQ

What is the maximum operating temperature for 74AUP2G3404FW4-7?

The device is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature reaching +150°C under worst-case power dissipation. This rating supports deployment in automotive cabin modules, industrial edge sensors, and outdoor IoT gateways without thermal derating.

Does 74AUP2G3404FW4-7 require external pull-up or pull-down resistors on unused inputs?

No external resistors are required: unused inputs must be tied directly to VCC or GND per the datasheet recommendation. The AUP family's high-input impedance (<0.75µA leakage) and Schmitt-trigger structure eliminate floating-input risks without added components.

Can 74AUP2G3404FW4-7 drive a 50pF load reliably?

Yes-the device maintains valid logic levels and timing with CL ≤ 50pF, though propagation delay increases to ~7.2ns at 3.3V (vs. 3.2ns at 5pF). Output drive remains within specification (VOL < 0.45V, VOH > 2.67V) up to ±4mA, supporting moderate fanout in compact PCB layouts.

Is the X2-DFN1010-6 package compatible with standard reflow profiles?

Yes-the FW4 package is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260°C. Its wettable flank design enables reliable solder joint inspection via AOI, and the 0.35mm pitch meets standard stencil aperture guidelines for Type 3 solder paste.
