error in model LM293D - open collector property of output not implemented?

[JJMC]

The comparator LM293D has an open collector output according to the datasheet.

I attempt to use that property to create a delay in the positive going response.

However, the output in the model goes hi without the external pull-up resistor that is required according to the datasheet and does not delay when attaching even a large capacitor to the minus rail.

Thanks for any help.

Hello Jan,

Can you attach your actual Multisim schematic file?

This should allow me to have a first look at the your experiencing and should also allow me to evaluate what might be going wrong.
