damage to the device. Furthermore, extended operation at these maximum
ratings may reduce the life of this device.
PERFORMANCE DATA
These performance parameters
are based on module operation at
25°C from a 3.0VDC supply unless
otherwise noted. Figure 2
illustrates the connections
necessary for testing and
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.

TYPICAL PERFORMANCE GRAPHS
ELECTRICAL SPECIFICATIONS
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
5 volts as a result of the required dropping resistor. Please verify that the minimum voltage will meet the
high threshold requirement of the device to which data is being sent.
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.
