NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit

board with maintained transverse airflow greater than 500 lfpm.

3 Level Digital Logic

S0, S1, and FSEL digital inputs are designed to sense 3

different logic levels designated as High “1”, Low “0” and

Middle “M”. With this 3−Level digital input logic 9 different

logic states can be detected.

S0, S1 and FSEL pins include an on chip 100 K (50 K /

50 K) resistor divider. No external application resistors are

needed to implement the 3−Level logic levels as shown in

table on the right:
