The HS-245RH/246RH/248RH radiation hardened triple line
transmitter and triple line receivers are fabricated using the
Intersil dielectric isolation process. These parts are identical in
pinout and function to the original HD-245/246/248. They are
also die size and bond pad placement compatible with the
original parts for those customers who buy dice for hybrid
assembly.
Each transmitter-receiver combination provides a digital
interface between systems linked by 100twisted pair,
shielded cable. Each device contains three circuits
fabricated within a single monolithic chip. Data rates greater
than 15MHz are possible depending on transmission line
loss characteristics and length.
The transmitter employs constant current switching which
provides high noise immunity along with high speeds, low
power dissipation, low EMI generation and the ability to
drive high capacitance loads. In addition, the transmitters
can be turned “off” allowing several transmitters to time-
share a single line.
Receiver input/output differences are shown in the table:

The internal 100cable termination consists of 50from
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. When used with shielded transmission
line, the transmitter-receiver system has very high immunity to
capacitance and magnetic noise coupling from adjacent
conductors. The system can tolerate ground differentials of
-2.0V to +20.0V (transmitter with respect to receiver).
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.

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.
