Notes: 1. At junction temperatures above those listed as Operating Conditions, all delay parameters increase by 0.3% per °C.
2. Although the present (1996) devices operate over the full supply voltage range from 3.0 V to 5.25 V, Xilinx reserves the right
to restrict operation to the 3.0 and 3.6 V range later, when smaller device geometries might preclude operation @ 5 V.
Operating conditions are guaranteed in the 3.0 – 3.6 V V
range.

configured with a tie option.
2. Total continuous output sink current may not exceed 100 mA per ground pin. Total continuous output source current may not
exceed 100 mA per V pin. The number of ground pins varies from the XC3142L to the XC3190L.

3. Not tested. Allows undriven pins to float High. For any other purpose, use an external pull-up.
