At 30 % activity on video port output.
In high-impedance state, the output buffer is set to repeater mode recopying the input logic state with a small current. The output current
changes from most negative to the most positive value at the triggering level which is internally set to V
pull-up or pull-down resistor must be lower than 18 k to have a stable output value of V
x = A, B, C or D.
Fast mode, 5 V tolerant.
5 V tolerant.
