NOTES:
1. 10/100KELT circuits are designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. The circuit is
in a test socket or mounted on a printed circuit board and traverse airflow greater than 500lfpm is maintained.
2. VIHCMR (Min) varies 1:1 with GND, VIHCMR (Max) varies 1:1 with VCC.
