Diodes Incorporated 74AUP2G07FZ4-7

Overview

74AUP2G07FZ4-7 from Diodes Incorporated is a dual non-inverting buffer with open-drain outputs, designed for level-shifting and wired-OR logic in ultra-low-power portable systems. It operates across 0.8V–3.6V supply, delivers −4mA output drive at 3.0V, features IOFF partial power-down protection, and supports Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V - used in battery-powered I²C bus extensions and voltage-level translation between mixed-supply domains.

For engineers reviewing the 74AUP2G07FZ4-7 datasheet, 74AUP2G07FZ4-7 pinout, 74AUP2G07FZ4-7 application, or 74AUP2G07FZ4-7 equivalent, key selection criteria include its 0.9µA max ICC at 3.6V, 1.2pF typical CPD, IOFF-enabled isolation during partial power-down, and compatibility with 0.35mm–0.5mm pitch DFN packages for space-constrained embedded designs.

Technical Context

This device implements two independent non-inverting buffers (A→Y) with open-drain outputs, enabling wired-AND/wired-OR configurations and bidirectional level translation without external pull-ups on the output side. Each input includes Schmitt-trigger action with 250mV typical hysteresis at 3.0V, improving noise immunity for slow-rising signals.

The IOFF circuit actively disables both outputs when VCC = 0V, blocking reverse current flow from powered downstream nodes into the unpowered IC - critical for hot-swap and multi-rail system partitioning. It is fully characterized from −40°C to +125°C and supports 200 ns/V minimum input transition rate.

FAQ

Can 74AUP2G07FZ4-7 drive a standard I²C bus at 400kHz?

Yes. At VCC = 3.3V, it sinks −4mA, which supports a 2.2kΩ pull-up on a 400pF bus - meeting I²C Fast Mode timing (≤3.5µs rise time). Its 0.9ns min/3.5ns max propagation delay at CL = 5pF ensures minimal added latency, and Schmitt inputs tolerate slower edge rates common in long-trace or capacitive bus environments.

What happens to the outputs when VCC is disconnected?

When VCC = 0V, the IOFF circuit activates, disabling both 1Y and 2Y outputs and limiting leakage to ±0.75µA maximum. This prevents reverse current flow from externally powered pull-up resistors or downstream devices, protecting unpowered circuit sections during hot-swap or partial shutdown - a key requirement in modular IoT hardware.

Is the X2-DFN1410-6 package compatible with standard reflow profiles?

Yes. The X2-DFN1410-6 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL1), supporting peak reflow temperatures up to 260°C. Its 0.5mm pad pitch and wettable flanks enable reliable solder joint inspection via automated optical inspection (AOI), and the 0.4mm profile allows placement beneath tall connectors in ultra-thin PCB stacks.

How does the Schmitt-trigger input improve system reliability?

The ~250mV hysteresis at VCC = 3.0V prevents multiple toggles caused by slow-rising signals or noise near the logic threshold - critical for mechanical switch inputs, thermistor-based comparators, or long-flex-cable sensor links. Unlike standard CMOS inputs, it guarantees clean, single-edge transitions even with 10–100ns input slew rates, eliminating need for external RC filtering or firmware debouncing.
