... Pull-Up Resistors The internal 100Ω cable termination consists of 50Ω from each input to ground. HS-248RH ‘‘party line’’ receivers have a Hi-Z input such that as many as ten of these receivers can be used on a single transmission line. Each transmitter input and receiver output can be connected to TTL and DTL systems ...

... For example, a 2mA change in transmitter current will produce a 100mV change in receiver voltage independent of the series transmission line resistance. The rise time at the receiver for a typical 50 foot cable (750pF) is approximately 30ns for a 2mA pulse. 3 HS-245RH, HS-246RH, HS-248RH (Continued) +5V 1/3 HS-245RH (NOTE) FIGURE 3.

... Receivers The HS-248RH “party-line” receiver presents a high impedance load to the transmission line allowing as many as ten HS-248RH receivers to be distributed along a line without excessive loading. Figure 3 shows a typical system of a transmitter, a terminating receiver and a party-line receiver. The transmission line is terminated in its characteristics impedance by an HS-246RH pair of 50Ω ...
