4. Electrical Specifications

Table 4.1. Electrical Specifications

VDDA = 3.0 V – 5.5 V (See Figure 3.1 for Si8285, Figure 3.2 for Si8286); Driver supply voltage = VDDB-VSSB, TA = –40 to +125 °C

unless otherwise noted. Minimum value of decoupling capacitors between VDDB and VMID and between VMID and VSSB is 1 μF.
