Maxim Integrated
Note 2: To provide a midlevel, leave the input open, or, if driven, put driver in high impedance. High-impedance leakage current
must be less than Q10A.
Note 3: IIN min due to voltage drop across the internal pullup resistor.
Note 4: Specified pin to ground.
Note 5: Specified pin to all supply/ground.
Note 6: Guaranteed by design and not production tested.
Note 7: Measured in serial link bit times. Bit time = 1/(30 x fPCLKIN) for BWS = 0. Bit time = 1/(40 x fPCLKIN) for BWS = 1.
AC ELECTRICAL CHARACTERISTICS (continued)
(VDVDD = VAVDD = 1.7V to 1.9V, VIOVDD = 1.7V to 3.6V, RL = 100I Q1% (differential), EP connected to PCB ground (GND),
TA = -40NC to +105NC, unless otherwise noted. Typical values are at VDVDD = VAVDD = VIOVDD = 1.8V, TA = +25NC)
