DS11195C-page 5 MCP41XXX/42XXX Absolute Maximum Ratings † VDD...................................................................................7.0V All inputs and outputs w.r.t. VSS ............... -0.6V to VDD +1.0V Storage temperature .....................................-60°C to +150°C Ambient temp. with power applied ................-60°C to +125°C ESD protection on all pins ..................................................≥ 2kV † Notice: Stresses above those listed under “maximum rat- ings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Expo- sure to maximum rating conditions for extended periods may affect device reliability. AC TIMING CHARACTERISTICS Electrical Characteristics: Unless otherwise indicated, VDD = +2.7V to 5.5V, TA = -40°C to +85°C. Parameter Sym Min. Typ. Max.

Max. clock frequency is therefore ~ 5.8 MHz based on SCK rise and fall times of 5 ns, tHI = 40 ns, tDO = 80 ns and tSU = 40 ns. 2: Applies only to the MCP42XXX devices. 3: Applies only when using hardware pins to exit software shutdown mode, MCP42XXX only. |
