2.3 DC Characteristics (Continued)
Electrical Characteristics: Extended (E): TAMB = -40°C to +125°C and High (H): TAMB = -40°C to +150°C;
V
DD = 4.5V to 5.5V, VIO = 1.8V to 5.5V (Note 2), RL = 60, CL = 100 pF; unless otherwise specified.
Characteristic Sym Min Typ Max Units Conditions
Note 1: Characterized; not 100% tested.
2: Only MCP2562FD has V
IO pin. For the MCP2561FD, VIO is internally connected to VDD.
3: -12V to 12V is ensured by characterization, tested from -2V to 7V.
