Diodes Incorporated 74AUP1G08SE-7

Overview

74AUP1G08SE-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT353 package, designed for ultra-low-power logic interfacing in battery-operated systems. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and includes Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V for noise-immune signal conditioning in portable electronics.

For engineers reviewing the 74AUP1G08SE-7 datasheet, 74AUP1G08SE-7 pinout, 74AUP1G08SE-7 application, or 74AUP1G08SE-7 equivalent, this device is selected for low-voltage logic level translation, enable/control gating in wearables and IoT edge nodes, and power-aware signal combining where static current < 0.9µA and dynamic CPD = 6.3pF are critical.

Technical Context

This CMOS AND gate implements standard Boolean Y = A • B logic with push-pull outputs and no internal pull-ups or open-drain configuration. Its IOFF circuit actively disables output terminals during power-down to block back-current flow between powered and unpowered domains - essential for mixed-voltage system partitioning.

The Schmitt-trigger input structure provides defined switching thresholds (VIH ≈ 0.8×VCC, VIL ≈ 0.3×VCC) and inherent noise immunity, enabling reliable operation with slow-rising or degraded signals (e.g., from mechanical switches or long PCB traces), while propagation delay ranges from 1.0ns (3.3V, CL=5pF) to 34.4ns (0.8V, CL=30pF).

FAQ

What is the minimum operating voltage for 74AUP1G08SE-7?

The device is fully specified down to 0.8V supply voltage, with guaranteed functionality including IOFF and Schmitt-trigger behavior across the entire 0.8V–3.6V range. At 0.8V, propagation delay increases to 17.0ns (CL=5pF), and output drive reduces to ±20µA - sufficient for driving high-impedance CMOS inputs in ultra-low-power states.

Does 74AUP1G08SE-7 require external pull-up resistors on its inputs or output?

No. The device uses true push-pull CMOS outputs and has no open-drain configuration, so no external pull-up is needed on Y. Inputs are CMOS-compatible with rail-to-rail voltage thresholds and built-in Schmitt action - no external biasing or pull-ups are required, even for slow or floating signals.

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

When VCC = 0V, the IOFF circuit disconnects both input and output terminals from the internal core, limiting I/O leakage to ≤0.6µA. This prevents current from flowing backward through the gate when adjacent powered ICs drive signals onto A, B, or Y pins - protecting against latch-up and unintended power domain coupling in multi-rail systems.

Can 74AUP1G08SE-7 be used with 1.2V or 1.8V microcontrollers?

Yes. The device is explicitly characterized at 1.2V and 1.8V supply voltages, delivering 2.4ns and 1.3ns typical propagation delay (CL=5pF), respectively, with full VIH/VIL thresholds scaled to VCC. Its 0.8V–3.6V range makes it ideal for interfacing with modern low-voltage MCUs, including ARM Cortex-M0+ and RISC-V cores operating at 1.2V or 1.8V.
