What is SN74AUP1G79DCKRE4 used for?
The SN74AUP1G79DCKRE4 is suited for signal latching, edge detection, and data synchronization in battery-powered IoT nodes, wearables, and portable medical devices where supply voltages as low as 0.8 V and standby power must be minimized. Its SC70-5 package and ultra-low quiescent current make it an ideal building block for low-power state machines and control logic in energy-harvesting and coin-cell-powered designs.

Frequently Asked Questions
How low a supply voltage can the SN74AUP1G79DCKRE4 operate at for energy-harvesting designs?
The SN74AUP1G79DCKRE4 belongs to the AUP ultra-low-power family, which is specified for operation down to approximately 0.8 V supply voltage, with a maximum of 3.6 V. This wide VCC range from 0.8 V to 3.6 V makes it compatible with energy-harvesting cells, single alkaline cells, and 3.3 V logic systems in IoT and wearable applications.
What output drive current does the SN74AUP1G79DCKRE4 provide and what does that limit in design?
The device sinks up to 1.7 mA and sources a comparable level, which is sufficient for driving CMOS inputs at 30 pF load but insufficient for directly driving LEDs or high-current loads. Designers targeting loads above 1.7 mA should add a buffer or driver stage, while the SN74AUP1G79DCKRE4 itself is optimized for low-power register and control-signal latching at the 0.8 V to 3.6 V supply range.
When would a designer choose the SN74AUP1G79DCKRE4 over a larger 74HC74 dual flip-flop?
The single-gate SN74AUP1G79DCKRE4 is preferred when only 1 flip-flop is needed and board space is constrained to a 5-pin SC70 footprint, avoiding the unused 50% of a 74HC74. Its AUP family supply range down to 0.8 V also allows operation in ultra-low-power modes not achievable with the 2 V minimum of standard 74HC, making it the right choice for coin-cell-powered or energy-harvesting IoT designs.
How compact is the SC70-5 package of the SN74AUP1G79DCKRE4 compared to an SOT-23-5?
The SC70-5 package measures approximately 2.0 mm × 2.1 mm with a 0.65 mm pitch, which is about 30% smaller in footprint area than the SOT-23-5 at 2.9 mm × 1.6 mm with 0.95 mm pitch. This size reduction is significant in densely packed PCBs found in hearing aids, smartwatches, and compact sensor nodes where sub-2 mm component placement is required.
