Diodes Incorporated 74AUP1G07FX4-7

Overview

74AUP1G07FX4-7 from Diodes Incorporated is a single-channel CMOS buffer/driver with open-drain output, designed for level-shifting and wired-OR logic in ultra-low-power portable systems. It operates across 0.8V–3.6V supply, delivers 4 mA sink current at 3.0V, features IOFF partial power-down protection, and integrates Schmitt-trigger inputs with ~250 mV hysteresis at VCC = 3.0V-used in battery-powered GPS receivers and SSD power sequencing.

For engineers reviewing the 74AUP1G07FX4-7 datasheet, 74AUP1G07FX4-7 pinout, 74AUP1G07FX4-7 application, or 74AUP1G07FX4-7 equivalent, key selection criteria include open-drain drive capability, sub-1 µA static ICC, IOFF-enabled system-level power gating, and DFN1409-6 footprint compatibility with high-density PCB layouts.

Technical Context

This device implements a positive-buffer Boolean function (Y = A) using advanced ultra-low-power (AUP) CMOS process technology. Its open-drain output enables bidirectional bus interfacing and voltage-level translation between disparate supply domains without external pull-ups in some configurations.

The integrated IOFF circuit actively disables I/O terminals during power-down, blocking reverse current flow up to ±3.5 µA over full temperature range. Schmitt-trigger inputs tolerate slow-rising signals (≤200 ns/V transition rate), eliminating need for external signal conditioning in noisy low-speed control paths.

FAQ

What is the maximum capacitive load the 74AUP1G07FX4-7 can drive while maintaining specified tPD?

At VCC = 3.3V and TA = +25°C, the device maintains tPD ≤ 3.6 ns (typical) up to CL = 5 pF. With CL = 30 pF, tPD increases to 9.7 ns (typical). For reliable timing closure in high-speed enable paths, keep total net capacitance-including trace, via, and input pin-below 10 pF.

Can the NC pins (4 and 6) be grounded or tied to VCC for improved thermal performance?

No. Pins 4 and 6 are internally unconnected; connecting them to any potential violates the X2-DFN1409-6 mechanical specification and risks die damage due to unintended current paths. Thermal performance relies solely on the exposed pad soldered to the PCB thermal land per AP02002 guidelines.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes. IOFF engages whenever VCC falls below approximately 0.2V, disabling both input and output circuitry. The specification guarantees ≤ ±3.5 µA leakage across –40°C to +125°C, ensuring safe isolation even during brown-out conditions in multi-rail systems.

Is the Schmitt-trigger hysteresis voltage dependent, and how does it scale with VCC?

Hysteresis is not linearly proportional to VCC. At VCC = 3.0V, it is typically 250 mV; at VCC = 1.2V, it reduces to ~120 mV. This behavior is confirmed in DS35149 Rev. 5–2 Table 5, ensuring consistent noise margin across the full operating range without recalibration.
