Notes:
1. RTAD 0/1/2/3/4 and RTADPAR ONLY.
2. ALL Inputs and Bidirectionals other than those in Note 1.
3. lOL max = 3mA / lOH max = -2mA TX INHIBIT 0/1 and TX DATA/DATA ONLY. IOL max = 2mA / lOH max = -1 mA. ALL
remaining Outputs and Bidirectionals.
4. Input Clock (running) = 6Mhz, ALL remaining Inputs are Open and ALL Outputs and Bidirectionals have no load.
5. -20-3 only. RTAD0,1,3 and RTADPAR Input Threshold equals 1/2 Vcc ±5%.
