The ISL33001MSOPEVAL1Z, ISL33002MSOPEVAL1Z and ISL33003MSOPEVAL1Z evaluation boards are designed to provide a quick and easy method for evaluating the ISL33001, ISL33002 and ISL33003 2-channel bus buffers.

Discrete NMOS transistors are used to produce the pull-down functions of a wired-AND bus. Each SDA/SCL pin on the buffer is connected to an external open-drain NMOS transistor. The evaluation board also contains connections for the bus pull-up resistor and load capacitance. The logic input pins on the ISL3300x IC can be held logic High by a pull-up resistor or driven dynamically with an external logic source.
