Applications
The SN74AUP1T32 is used in IoT sensor nodes and wearable devices where a single OR gate is needed without the overhead of a multi-gate IC, minimizing both board space and quiescent current draw. Its multi-voltage input capability allows it to combine logic signals from 1.8 V microcontrollers and 3.3 V peripherals onto a single 3.3 V output rail without additional level translators. The device also serves in portable medical monitors and Bluetooth accessories for interrupt combining, enable signal merging, and simple combinational logic in ultra-compact PCB designs.

Frequently Asked Questions
Which input voltage levels does the SN74AUP1T32 accept, and what is its output voltage level?
The SN74AUP1T32 accepts input signals at 1.8 V, 2.5 V, or 3.3 V logic levels and produces a fixed 3.3 V CMOS output. This makes it a useful single-gate translator when combining signals from a 1.8 V microcontroller with a 3.3 V peripheral, eliminating the need for a separate bidirectional level-shift IC for simple unidirectional OR logic.
For a portable glucose monitor PCB, how small is the SN74AUP1T32's package footprint?
The SN74AUP1T32DCKR is housed in a 5-pin SOT-23 package with a PCB footprint of approximately 2.9 mm x 1.6 mm. This is one of the smallest standard logic packages available, making it suitable for space-critical designs in portable medical devices, hearing aids, and wearable sensors where every square millimeter of board area is at a premium.
How does the AUP logic family differ from standard AHC or LVC logic families in terms of power consumption?
The AUP (Advanced Ultra-low Power) family is designed for substantially lower quiescent current than AHC or LVC families, typically achieving static supply current below 0.1 µA compared to several microamps for LVC devices. This quiescent current advantage is critical in always-on monitoring circuits and energy-harvesting applications where the logic IC must not significantly drain the battery when inputs are static.
Can the SN74AUP1T32 be used to combine two interrupt signals from different ICs onto a single microcontroller GPIO pin?
Yes, the SN74AUP1T32 is well-suited for interrupt combining by connecting two open-drain or push-pull interrupt outputs to its two inputs. When either interrupt source asserts HIGH, the OR gate outputs HIGH to the microcontroller GPIO, which then reads the individual sources via I2C or SPI to determine which generated the interrupt. The 4 mA output ensures the microcontroller's input capacitance of up to 10 pF is driven cleanly.
What output sink current does the SN74AUP1T32 provide, and what fanout can it support?
The SN74AUP1T32 provides a maximum output sink current (IOL) of 4 mA. In a 3.3 V CMOS system where each CMOS input draws below 10 µA, this 4 mA drive can support a fanout of several hundred CMOS inputs in static conditions. For dynamic fanout with fast switching, the number of loads is limited by the output capacitance budget, typically 50 pF to 100 pF to maintain sub-5 ns propagation delay.
