Diodes Incorporated 74AUP1G07SE-7

Overview

74AUP1G07SE-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 from 0.8V to 3.6V, delivers 4 mA sink current at 3.0V, features IOFF partial power-down protection, and includes Schmitt-trigger inputs with ~250 mV hysteresis at VCC = 3.0V - enabling robust interfacing in battery-powered tablets, e-readers, and wearables.

For engineers reviewing the 74AUP1G07SE-7 datasheet, 74AUP1G07SE-7 pinout, 74AUP1G07SE-7 application, or 74AUP1G07SE-7 equivalent, key selection criteria include its 0.8–3.6V supply range, IOFF-enabled system-level power sequencing, sub-1 µA static ICC, open-drain flexibility for mixed-voltage bus driving, and SOT353 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a non-inverting buffer function (Y = A) with an open-drain output stage, requiring an external pull-up resistor for logic-high assertion. Its IOFF circuit actively disables output leakage when VCC = 0V, preventing back-current flow during partial power-down - critical for multi-rail SoC subsystems.

Schmitt-trigger inputs provide noise immunity with input thresholds scaling with VCC (e.g., VIH = 0.8×VCC at 0.8–1.65V), while propagation delay ranges from 0.8 ns (typ, 3.3V, CL = 5pF) to 24.6 ns (0.8V, CL = 30pF), supporting both high-speed signaling and low-voltage energy harvesting interfaces.

FAQ

Can the 74AUP1G07SE-7 drive a 10 kΩ pull-up resistor to 3.3V while maintaining valid logic levels?

Yes. With IOL = 4 mA at VCC = 3.0V and VOL ≤ 0.44 V (max), the output voltage drop across a 10 kΩ pull-up is negligible (< 0.04 V), ensuring solid LOW-level assertion. The device's open-drain structure inherently supports arbitrary pull-up voltages up to 4.6V, independent of VCC.

Does the NC pin (Pin 4) require grounding or can it be left floating?

Pin 4 is internally unconnected and must remain unpopulated or electrically floating - no grounding, routing, or soldering is permitted. Connecting it risks internal damage or unpredictable behavior, as confirmed by Diodes' AP02002 pad layout guidelines and DS35149 Rev. 5-2 pin descriptions.

How does the IOFF feature behave when VCC is ramping during power-up?

IOFF activates when VCC falls below ~0.2V, clamping output leakage to ±0.5 µA maximum. During power-up, the output remains in high-impedance state until VCC exceeds the minimum functional threshold (~0.8V), preventing glitch-induced bus contention in sequenced power systems.

Is the Schmitt-trigger hysteresis voltage fixed or proportional to VCC?

Hysteresis is VCC-proportional: at VCC = 3.0V, it is typically 250 mV; at VCC = 1.2V, it scales to ~100 mV. This maintains consistent noise margin across the full 0.8–3.6V operating range, as verified in DS35149 Table 5 (Electrical Characteristics) under VIH/VIL test conditions.
