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. CAMDs PAC27A88 is available in 20-pin small outline packages for space saving and manufacturing efficiency.

The absolute maximum ratings are limiting values, to be applied individually, beyond which the device may be permanently damaged. Functional operation under any of these conditions is not guaranteed. Exposing the device to its absolute maximum rating may affect its reliability.
