Logic Electrical Characteristics Digital DC Characteristics Unless otherwise noted, these specifications apply for +Vs=+3.3 Vdc. Boldface limits apply for TA=TJ=TMIN to TMAX; all other limits TA=TJ=+25°C, unless otherwise noted. SYMBOL PARAMETER CONDITIONS TYPICAL LIMITS UNITS VIN (1) Logical “1” Input Voltage +Vs× 0.7 +Vs + 0.5 V (min) V (max) VIN (0) Logical “0” Input Voltage -0.3 +Vs×0.3 V (min) V (max) IIN (1) Logical “1” Intput Current VIN=5V 0.005 1.0 µA IIN (0) Logical “0” Intput Current VIN=0V -0.005 -1.0 µA CIN All Digital Inputs 20 pF IOH High Level Output Current VOH=5V 100 µA (max) VOL Low Level Output Voltage IOL=3mA 0.4 V (max) tOF Output Fall Time CL=400pF,IO=3mA 250 ns (max) SMBus Digital Switching Characteristics Unless otherwise noted, these specifications apply for +Vs = +3.3 Vdc and CL (load capacitance) on output lines = 80pF unless otherwise specified. Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = +25°C, unless otherwise noted. The switching characteristics of the G751 fully meet or exceed the published specifications of the SMBus. The fol- lowing parameters are the timing relationships between SMBCLK and SMBDATA signals related to the G751. They are not the SMBus specifications.
