Transmitter
The HS-245RH transmitters have two inputs per transmitter,
either of which is low while the other is open during normal
operation and both inputs are open during standby. For
optimum transmitter performance, the “off” input should be
open circuit rather than being pulled towards +5V, because
this will reduce the “on” output data current. On the other
hand, the “on” and “off” output data current will increase if
the “off” input is held below its open circuit voltage. Open
collector gates such as the 7401 and 7403 or 7405 Hex-
Inverter are suitable for driving the HS-245RH transmitter
inputs. By using 2-input gates as shown in Figure 6, an
enable line can be provided so that more than one
transmitter may be connected to a line for time sharing.
When the enable line is low the transmitter will be disabled
and will present a high impedance to the transmission line
as well as requiring very little power supply current.
Complementary input signals may be derived from high
speed inverter gates as shown, or by using the
complementary outputs of a flip-flop. When the transmitter is
connected near the midpoint of a long transmission line or to
a line with terminations at both ends, two transmitter
sections should be paralleled with respective inputs and
outputs connected together in order to drive the reduced
impedance. This parallel transmitter technique can also be
used to increase the data rate on long transmission lines.
