I am looking at a redesign of a circuit due to needing a higher sinking current than the 40 mA per driver. The circuit that I am looking at parallels three of the output drivers to compensate for the need to drive a relay coil of about 70 Ohms that consumes approximately 72 mA. What I am wondering is that if it is OK to parallel all six of the output drivers in order to sink 240 mA? My thinking is that it is not the best way to address this issue. My thinking is that a single driver should be used in conjunction with a resistor on the collector side as a voltage divider or if there is another family of ICs that I should be looking for this application. I would like to stay with the open collector configuration in a 14 pin dip.
