The SN74LV07ADR from Texas Instruments is a hex buffer\/driver with open-drain outputs designed for 2V to 5.5V VCC operation. It performs the Boolean function Y = A in positive logic, with overvoltage-tolerant inputs and outputs accepting voltages up to 5.5V. The open-drain outputs enable wired-OR connections and mixed-voltage interfacing.<\/p>\n

Open-drain outputs accept voltages up to 5.5V, enabling I2C level shifting and wired-OR connections. Overvoltage-tolerant inputs and Ioff circuitry support mixed-voltage systems, partial power-down, and hot-plug applications. Low quiescent current (20uA max) with -40 to 125 C operation.","working_principle":"Each of the six channels is a non-inverting buffer with open-drain output. When input A is high, the output NMOS transistor turns on, pulling the output low through the external pull-up resistor. When input A is low, the output is high-impedance, allowing the external pull-up resistor to set the voltage level. This enables level shifting (e.g., 3.3V logic driving a 5V bus) and wired-OR configurations where multiple open-drain outputs share a single pull-up resistor.","pin_description":"
