General Description

that are each capable of sinking or sourcing current. Each

output has 15 sink and 15 source settings that are pro-

size of each output is determined by an external resistor

that can adjust the output current over a 4:1 range.

The output pins, OUT0 and OUT1, power-up in a high-

impedance state.

Applications
