Opto-isolated output electric feature can be shown in Table 3-5 (The external voltage
is 3.3 V and the external resistance is 1 K.)
Table 3-5 Output Electric Feature
Parameter Symbol Value
Output Logic Low Level VL 575mV
Output Logic High Level VH 3.3V
Output Rising Time TR 8.4us
Output Falling Time TF 1.9us
Output Rising Delay TDR 16.6us
Output Falling Delay TDF 3.6us
Table 3-6 shows the corresponding current and the parameter of output logic low level
when the opto-isolated outputs the different external voltage and resistance.
