Product Description
CAMD’s P/Active 27A88 is an 8 channel, open drain driver with low ON resistance and integrated protection diodes for inductive load switching. Each output can sink 40mA and all outputs may be active simultaneously. The circuit has two VDD connections for separation of the logic (VDDIN) and load (VDDOUT) supplies. A logic high on an input causes the corresponding output driver to turn ON and sink current from the load. A logic low on an input causes the corresponding output driver to turn OFF. When the switching inductive loads, the output protection diodes clamp the outputs to VDDOUT All inputs have pull downs to insure that the outputs are OFF when the inputs are open circuited. The inputs are fully compatible with CMOS logic and allow the PAC27A88 to be driven directly from microcontrollers and ASICs. CAMD’s PAC27A88 is available in 20-pin small outline packages for space saving and manufacturing efficiency.
