Diodes Incorporated 74AUP1G32SE-7

Overview

74AUP1G32SE-7 from Diodes Incorporated is a single 2-input positive OR gate in SOT353 package, operating across 0.8V–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 electronics for logic-level signal combining.

For engineers reviewing the 74AUP1G32SE-7 datasheet, 74AUP1G32SE-7 pinout, 74AUP1G32SE-7 application, or 74AUP1G32SE-7 equivalent, key selection criteria include ultra-low static current (<0.9µA), wide VCC range compatibility, IOFF-enabled system power sequencing, and input tolerance to slow edge rates in space-constrained mobile designs.

Technical Context

This Advanced Ultra Low Power (AUP) CMOS device implements a standard positive-logic OR function (Y = A + B) with push-pull output stage. Its Schmitt-trigger inputs provide 250mV typical hysteresis at VCC = 3.0V, enabling robust operation with slow-rising/falling signals without external conditioning.

The IOFF circuit actively disables outputs during partial power-down, blocking reverse current flow when VCC = 0V while inputs or outputs remain biased. It is fully characterized from –40°C to +125°C and supports load capacitances up to 30pF with propagation delays as low as 1.0ns (typical) at 3.3V/5pF.

FAQ

What is the minimum operating voltage for 74AUP1G32SE-7?

The device is fully specified down to 0.8V supply voltage, with guaranteed functionality including IOFF and Schmitt-trigger behavior across the full –40°C to +125°C temperature range. At 0.8V, propagation delay increases to 16.8ns (typical, CL=5pF), and output drive reduces to ±20µA, but logic thresholds remain valid per VIH/VIL specifications.

Does 74AUP1G32SE-7 require external pull-up or pull-down resistors?

No. The device features a push-pull output stage that actively drives both high and low states, eliminating the need for external pull-up resistors. Unused inputs must be tied to VCC or GND per datasheet recommendation (Note 8) to prevent floating nodes and excess current consumption.

How does IOFF protect the device during partial power-down?

When VCC = 0V, the IOFF circuit disables both output transistors, presenting a high-impedance state at Y regardless of A/B input voltages. This prevents reverse current flow from powered downstream circuits into the unpowered gate, avoiding potential damage or system malfunction during staged power sequencing.

Can 74AUP1G32SE-7 drive a 15pF load at 3.3V with sub-5ns delay?

Yes. At VCC = 3.3V and CL = 15pF, the typical propagation delay is 3.1ns (TA = +25°C), well within the 5ns target. The maximum delay is 4.9ns under worst-case conditions (–40°C to +125°C), maintaining timing margin for most portable interface applications.
