All input ports are continuously monitored for state chang - es (transition detection). Transitions are alerted through the open-drain, 5.5V-tolerant INT output. The MAX7328 and MAX7329 versions differ only by their slave ID address ranges. The MAX7328 has a slave ID range of 0100xxx (0x20 to 0x27).

WebIf at least one of the outputs is in logic 0 state (active), the circuit sinks the current and brings the line to low voltage. You can use open-drain output if you are connecting … 'Open drain output' is analogous to open collector operation, but uses a n-type MOS transistor (MOSFET) instead of an NPN. An open drain output connects to ground when a high voltage is applied to the MOSFET's gate, or presents a high impedance when a low voltage is applied to the gate. The voltage in this high impedance state would be floating (undefined) because the MOSFET is not conducting, which is why open drain outputs require a pull-up resistor connecte… onscrollstart https://ugscomedy.com
