Note 7: Typical values are for V_CC = 5.0V and T_A = 25˚C and are meant for reference only.
Note 8: Refer to Functional Truth Tables for control input definition.
Note 9: Test configuration should be connected to only one transceiver at a time due to the high current stress caused by the V_I voltage source when the output con-
nected to that input becomes active.
