Note 1:
Driver inputs are TTL level compatible.
Note 2:
Unused receiver inputs are terminated with 30k to ground. In addition, R2 and R3 are always
terminated by a 103
differential impedence (see Block Diagram on page 7).
Note 3:
Receiver Outputs are CMOS level compatible and have a weak pull up to V
IN
when Z.
