Boldface limits apply at the defined temperature extremes.) (Note 1) AC ELECTRICAL CHARACTERISTICS—1.8V OPERATION (VDD = 1.8V, VSS = 0V, VCM = 0V, RL = 5.1kI connected to VDD, typical values are at TA = +25NC, unless otherwise noted. Boldface limits apply at the defined temperature extremes.) (Note 1) Note 1: All devices are production tested at TA = +25NC. All temperature limits are guaranteed by design. Note 2: Supply current when output is high. Note 3: Input overdrive is the overdrive voltage beyond the offset and hysteresis-determined trip points.
