What are the key features of SN74AUC1G86DCKRE4?
- Single 2-input XOR gate in AUC low-voltage logic family operating from 0.8 V to 2.7 V supply, enabling direct interfacing with 1.8 V and sub-1 V logic systems
- Ultra-compact 5-pin SC-70 package with approximately 2 mm × 2.1 mm footprint, minimising board area in wearable and IoT designs
- 5 mA IOL/IOH output drive with 15 pF rated load capacitance and RoHS e4 lead-free qualification in tape-and-reel packaging
What is SN74AUC1G86DCKRE4 used for?
SN74AUC1G86DCKRE4 is suited for parity detection and comparison circuits in battery-powered IoT nodes and wearables where the 0.8 V minimum supply aligns with near-threshold or 1.0 V logic rails. Its XOR function is also used for clock inversion and differential-to-single-ended signal conversion in low-voltage FPGA and processor interfacing designs. The tiny SC-70 footprint makes it practical for space-constrained PCBs in portable medical monitors and smart sensors.

Frequently Asked Questions
How low a supply voltage can SN74AUC1G86DCKRE4 operate from and what logic levels does that enable?
SN74AUC1G86DCKRE4 operates from a supply of 0.8 V to 2.7 V. At 1.8 V VCC, the input high threshold is approximately 0.65 × VCC = 1.17 V and input low is 0.35 × VCC = 0.63 V, directly compatible with 1.8 V LVCMOS logic used in modern application processors. At the 0.8 V minimum, it interfaces with sub-1 V near-threshold logic found in energy-harvesting sensor designs without any level-shifting circuitry.
In what circuit role does a single XOR gate like SN74AUC1G86DCKRE4 replace a more complex gate arrangement for clock inversion?
An XOR gate with one input tied to logic HIGH acts as a programmable inverter: when the control input is HIGH, output equals NOT(data); when LOW, output passes data unchanged. This allows SN74AUC1G86DCKRE4 to replace a discrete NOT gate plus a 2-input MUX in dynamic clock-phase-switching circuits. In a 1.8 V clock tree with 15 pF PCB trace capacitance, the single 5-pin SC-70 device handles the switching with propagation delay under 2 ns typical at VCC = 1.8 V.
How does the SC-70 package of SN74AUC1G86DCKRE4 compare to SOT-23 for PCB density in a multi-gate glue-logic array?
The 5-pin SC-70 package measures 2.0 mm × 2.1 mm with 0.65 mm pin pitch, versus a 5-pin SOT-23 at 2.9 mm × 1.6 mm—the SC-70 footprint is roughly 35% smaller by area. In a glue-logic array with 8 single-gate devices, switching to SC-70 from SOT-23 reclaims approximately 50 mm² of PCB area, significant on a 4-layer board where routing channels are constrained. Both packages support reflow soldering compatible with standard lead-free SAC305 solder paste profiles.
When is SN74AUC1G86DCKRE4 a better choice than SN74LVC1G86 for a 1.8 V sensor MCU interface?
SN74AUC1G86DCKRE4 (AUC family) operates down to 0.8 V versus 1.65 V minimum for SN74LVC1G86 (LVC family), making AUC the only choice when the MCU rail is below 1.65 V. At 1.8 V, AUC also achieves lower propagation delay (typically under 2 ns versus 3 ns for LVC) and lower quiescent current, reducing power consumption by 30% to 50% in always-on sensor interface circuits. The 5-pin SC-70 package is identical in footprint between the two parts, so migration requires only a BOM change.
