(High speed limit determined by
asynchronous sampling rate. Jitter is fixed @
320nsec. Higher data rates (up to 1M
baud
maximum) are possible if equipment driven
has greater jitter tolerance).

Input Voltage Range: ....................................... 100mV to 12V differentially across “+” and “-“
data input pins or 50mV to 6V on either input
with respect to GND (50mV internal hysteresis)
Input Common Mode Range: ...................... +1.65Vdc ±10%
