This pre-assembled module comprises 8 independent BC457 NPN transistor outputs configured as open collector sinking drivers for general low current applications. Each transistor can handle a load of up to 100mA.
The transistors are configured as two separate blocks of four drivers each. Each output can be controlled using standard logic level signals from for example a microcontroller or the ABC Atmel AVR Mini Board.
