 		 #38847 - 4051 open collector ports.
Hi, I am using a Atmel 4051 for a small project and need to use the two open collector ports p1.0 and p1.1 to switch LEDs.

The docs say they need pull-up resistors to VCC, but when I do this the pull-ups switces the LEDs on permenantly. If I remove the pull-ups, the port doesn't work.

Any help of ideas would be appreciated.

Thanx
Roelf Pringle
