Notes: 1. With no output current loads, no active input or Longline pull-up resistors, all package pins at VCC or GND, and the LCA
device configured with a tie option.
2. Total continuous output sink current may not exceed 100 mA per ground pin. The number of ground pins varies from two for
the XC3120A in the PC84 package, to eight for the XC3195A in the PQ208 package.
3. Not tested. Allows an undriven pin to float High. For any other purpose, use an external pull-up.
