Notes
1. The KH2 can utilize a 4.3 to 5.2VDC supply provided a 330-ohm resistor is placed in series with VCC.
2. Into a 50-ohm load.
3. When operating from a 5V source, it is important to consider that the output will swing to well less than
4. For BER of 10 -5 at 1,200bps.
5. Characterized, but not tested.
6. Time to valid data output.
7. Maximum drive capability of data outputs.

operation. It is recommended all
ground pins be connected to the
ground plane. The pins marked NC
have no electrical connection and
are designed only to add physical
support.
