Typical Operating Characteristics
(VDD = VL = +3.3V, circuit and components of Figure 1, all transmitters loaded with 3k,TA = +25°C, unless otherwise noted.)
TIMING CHARACTERISTICS
(VDD = +3.0V to +3.6V, VL = +3.3V, circuit and components of Figure 1, TA = TMIN to TMAX, unless otherwise noted. Typical values
are at VDD = +3.3V, TA = +25°C.)
Note 2: Guaranteed by design and not production tested.
Note 3: No load on REG or transmitter outputs.
