Texas Instruments SN74AUP3G07DQER

Overview

SN74AUP3G07DQER from Texas Instruments is a triple non-inverting buffer/driver with open-drain outputs, designed for low-power point-to-point signal routing in battery-powered systems. It operates across 0.8 V to 3.6 V, delivers 4.3 ns max propagation delay at 3.3 V (CL = 15 pF), consumes ≤0.9 µA static current, and supports Ioff partial-power-down mode - enabling use in mixed-voltage I²C bus level-shifting and GPIO expansion.

For engineers reviewing the SN74AUP3G07DQER datasheet, SN74AUP3G07DQER pinout, SN74AUP3G07DQER application, or SN74AUP3G07DQER equivalent, key selection criteria include its 3.3-V-optimized ultra-low power consumption, open-drain output compatibility with wired-AND/wired-OR topologies, 1.5 pF typical input capacitance for high-speed signal integrity, and X2SON-8 (DQE) package suitability for space-constrained portable designs.

Technical Context

The SN74AUP3G07DQER implements three independent non-inverting buffers, each with an open-drain output stage that requires an external pull-up resistor. Its AUP logic family uses optimized CMOS process technology to achieve sub-1 µA ICC across the full 0.8–3.6 V VCC range while maintaining robust noise margins and fast switching.

It features Ioff circuitry that disables outputs during partial power-down, preventing backflow current when VCC = 0 V but inputs remain active. The device meets JESD 78 Class II latch-up performance (>100 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM), supporting reliable operation in handheld and wearables environments.

FAQ

What is the maximum operating frequency supported by SN74AUP3G07DQER?

The SN74AUP3G07DQER does not specify a maximum clock frequency, as it is a combinational buffer-not a clocked device. Its propagation delay is characterized up to 2.8 ns (3.3 V, CL = 15 pF), supporting reliable operation in digital signal paths toggling at ≤350 MHz under typical load conditions. System-level timing depends on external pull-up value and capacitive loading.

Can SN74AUP3G07DQER be used with a 5-V pull-up resistor?

Yes - SN74AUP3G07DQER outputs are open-drain and tolerate up to 3.6 V on outputs (VO) when powered, but the datasheet specifies VO ≤ VCC + 0.5 V in driven states. With VCC = 3.3 V, a 5-V pull-up is acceptable only if the output remains in high-impedance (not actively pulled low); otherwise, external clamping or level-shifting is required to avoid overstress.

Does SN74AUP3G07DQER require external pull-up resistors on all outputs?

Yes - all three outputs (1Y, 2Y, 3Y) are open-drain and require external pull-up resistors to establish a defined logic-high voltage. Typical values range from 2.2 kΩ (for speed-critical I²C) to 100 kΩ (for ultra-low-power sensor wake-up lines), selected based on rise time, bus capacitance, and current budget.

Is SN74AUP3G07DQER compatible with 1.2-V logic inputs?

Yes - SN74AUP3G07DQER supports VIH as low as 0.65 × VCC. At VCC = 1.2 V, VIH(min) = 0.78 V, making it fully compatible with 1.2-V CMOS outputs. Its 0.8–3.6 V VCC range and 3.6-V input tolerance ensure interoperability across sub-1.8-V logic families without level translation.

What is the thermal performance of the X2SON-8 (DQE) package for SN74AUP3G07DQER?

The X2SON-8 (DQE) package for SN74AUP3G07DQER has a θJA of 261°C/W (JEDEC Std). With its exposed thermal pad tied to PCB ground plane, actual thermal resistance drops significantly - typically ≤65°C/W with 200 mm² copper pour. This enables continuous operation at 85°C ambient even at 20 mA per output under proper layout.
