HS-246RH Radiation Hardened Triple
HS-248RH Radiation Hardened Triple
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 100 twisted 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 100 cable termination consists of 50 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. 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.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-96722 and 5962-96723. A “hot-
