Product details
Overview
SN74LVC1G86DCKR from Texas Instruments is a single 2-input exclusive-OR gate IC performing Y = AB + ĀB in positive logic, designed for 1.65V–5.5V VCC operation with ±24mA output drive at 3.3V, 4ns max propagation delay at 3.3V/15pF, and Ioff-enabled partial-power-down protection. It serves as a true/complement selector in bus interface and level translation circuits.
For engineers reviewing the SN74LVC1G86DCKR datasheet, SN74LVC1G86DCKR pinout, SN74LVC1G86DCKR application, or SN74LVC1G86DCKR equivalent, key selection criteria include overvoltage-tolerant inputs (up to 5.5V), SC70-5 package footprint, –40°C to +125°C operating range, and balanced CMOS push-pull output drive capability.
Technical Context
This device implements a single XOR logic function with standard CMOS inputs and balanced high-drive push-pull outputs. Its Ioff circuitry ensures outputs enter high-impedance state during power-down, preventing back-drive current flow.
The SC70-5 package supports space-constrained designs while maintaining full compatibility with 1.65V–5.5V supply rails. Input tolerance up to 5.5V enables robust down-translation between mixed-voltage domains without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| tpd (max) | 4ns at 3.3V/15pF - enables reliable timing in sub-100MHz digital control paths |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple LVC loads or small capacitive traces without buffering |
| Ioff Leakage | ±10µA max - guarantees safe isolation during partial power-down in multi-rail systems |
| Input Voltage Tolerance | Up to 5.5V regardless of VCC - eliminates need for external clamping in mixed-supply interfaces |
| Operating Temp | –40°C to +125°C - qualified for automotive under-hood and industrial motor-control environments |
| ICC (max) | 15µA at –40°C to +125°C - ultra-low static power for always-on monitoring circuits |
Pinout & Package
SN74LVC1G86DCKR uses the SC70-5 (DCK) package: 2.00mm × 1.25mm footprint, 0.65mm pitch, 5-terminal surface-mount configuration optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input A | Primary XOR input; accepts 0–5.5V signals independent of VCC |
| 2 (B) | Input B | Secondary XOR input; same overvoltage tolerance and logic threshold as Pin 1 |
| 3 (GND) | Ground | Reference return path for all internal logic and output stages |
| 4 (Y) | Output Y | True/complement result of A ⊕ B; drives ±24mA at 3.3V with rail-to-rail swing |
| 5 (VCC) | Supply | Positive supply rail (1.65–5.5V); powers internal logic and enables Ioff behavior when at 0V |
Key Features

|---|---|
| NanoFree™ SC70 package | Die-as-package construction reduces footprint to 2.00mm × 1.25mm - ideal for wearables and compact audio modules |
| Ioff partial-power-down | Outputs disable to high-Z when VCC = 0V, blocking back-current flow in hot-swap or multi-supply systems |
| Overvoltage-tolerant inputs | Accepts 5.5V inputs at any valid VCC - enables direct connection to 5V peripherals without level-shifting components |
| Balanced CMOS push-pull outputs | Sinks and sources equal current (±24mA @ 3.3V), ensuring symmetrical rise/fall times and reduced signal distortion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | SOT-23-5 package (2.90mm × 1.60mm); higher RθJA (357.1°C/W vs. 371°C/W); identical electrical specs | Less space-constrained layouts where thermal mass improves power dissipation | Select when board layout allows larger footprint and thermal performance outweighs size constraints |
| 74LVC1G86GW,125 | SC70-5 from Nexperia; 3.3V-only VCC range (1.65–3.6V); 4.5ns tpd at 3.3V/15pF; ±24mA drive | Not suitable for 5V-tolerant or wide-VCC applications requiring 4.5–5.5V operation | Choose only for cost-sensitive 3.3V-only designs where TI's 5.5V tolerance is unnecessary |
Compared with SN74LVC1G86DBVR and 74LVC1G86GW,125, the SN74LVC1G86DCKR uniquely combines SC70-5 miniaturization, full 1.65–5.5V operation, and 5.5V input tolerance - making it the only option qualified for both space-critical and mixed-voltage industrial applications.

FAQ
What is the maximum input voltage rating for SN74LVC1G86DCKR?
The SN74LVC1G86DCKR supports input voltages up to 5.5V regardless of VCC level, enabling direct interfacing with 5V peripherals while operating from lower supply rails like 1.8V or 3.3V. This overvoltage tolerance is explicitly specified in Section 5.1 Absolute Maximum Ratings and confirmed in Section 7.3.5 of the datasheet.
Does SN74LVC1G86DCKR support partial power-down functionality?
Yes, SN74LVC1G86DCKR implements Ioff circuitry that disables outputs and limits leakage to ±10µA when VCC = 0V. This prevents damaging back-current flow in multi-rail systems during hot-swap or standby modes, as detailed in Section 7.3.4 and Table 5.5 of the datasheet.
What is the propagation delay of SN74LVC1G86DCKR at 3.3V?
At 3.3V VCC with a 15pF load, SN74LVC1G86DCKR has a maximum propagation delay (tpd) of 4ns, as specified in Section 5.6 Switching Characteristics. This value is measured across the full –40°C to +125°C operating range and applies to both A→Y and B→Y transitions.
Which package type does SN74LVC1G86DCKR use?
SN74LVC1G86DCKR uses the SC70-5 (DCK) package: a 5-pin, surface-mount package measuring 2.00mm × 1.25mm with 0.65mm lead pitch. This NanoFree™ package is confirmed in the Package Information table and Orderable Addendum of the datasheet.
Can SN74LVC1G86DCKR operate from a 1.8V supply?
Yes, SN74LVC1G86DCKR is fully specified for operation from 1.65V to 5.5V VCC. At 1.8V, it delivers 2.1ns minimum / 9.1ns maximum tpd (CL = 15pF) and supports VIH/VIL thresholds scaled to VCC, as defined in Section 5.3 Recommended Operating Conditions.
