• Description: Radiation Hardened Triple Line(party-Line) Transmitter
• Manufacturer: INTERSIL [Intersil Corporation]

the grounded input of the transmitter, and is less than 25V
negative with respect to the transmitter VCC. The current
mode system is totally unaffected by ground differential
noise of +2V at frequencies as high as 1MHz.
Propagation Delay
The worst case propagation delay of a transmitter and
receiver, connected as shown in Figure 6, can be
determined by adding the maximum delay shown on the
data sheet for the transmitter and receiver. These overall
switching characteristics are shown in Table B. For the entire
system, however, the propagation delay of the transmission
line must also be considered. This delay, of course, depends
on the length of the line and the characteristics of the line,

NOTES:
1. HS-246RH does not have 6K output pull-up resistors.
2. HS-248RH does not have 50 input termination resistors.
