EPM3032ALC44-10N Settings for Quartus II

Hi, I'm a first time user of the Altera CPLD chip EPM3032ALC44-10N and Quartus II software. I have a design that doesn't use all the I/O's. I am also driving HCT cmos chips with the EPM3032A outputs....

Your settings are appropriate.

You could also use "As input tri-stated with weak pull-up" if that device family supports a weak pull-up.

HCT logic levels are TTL logic levels, so the 3.3V MAX output levels will be compatible with the HCT input logic levels.

Cheers,

Dave
