Notes:
1. Operation in excess of any one of these parameters may result in
permanent damage.
2. Mounted on 5 cm x 5 cm x 0.16 mm glass epoxy PCB
(TA = Max TOP).
3. Mounted on 50 cm x 50 cm x 1.6 mm glass epoxy PCB with
copper film (TA = Max TOP).

Attention:
Due to high frequency characteristics, the physical circuit layout is very
critical. Supply voltage line bypass, double-sided printed-circuit board,
and wide-area ground line layout are necessary for stable operation.
Two signal resistors connected to both inputs and two load resistors
connected to both outputs should be balanced for stable operation.
