Product Overview
The SN74AHC86 is a Texas Instruments quad 2-input exclusive-OR gate device. In positive logic, each gate implements Y = A XOR B, providing four independent XOR functions with two inputs per gate. The device is categorized as Signal_Chain content here and is specified for logic-level signal processing functions that require exclusive-OR behavior.
Recommended operating conditions cover a 2 to 5.5 V supply range, 0 to 5.5 V input voltage, and 0 to VCC output voltage. The SN74AHC86 version is specified for -40 to 125 °C operating free-air temperature, while the related SN54AHC86 range is -55 to 125 °C. Input thresholds are specified at 2 V, 3 V, and 5.5 V VCC levels.
