ESCRIPTION
:
Maxwells's 358 8-Channel single-ended (1 of 8) multiplexers
with fault protection features a greater than 50 krad (Si) total
dose tolerance, depending upon space mission. Using a
series N-channel, P-channel, N-channel structure, these multi-
plexers provide significantly improved fault protection. If the
power supplies to the fault-protected multiplexer are inadvert-
ently turned off while input voltages are still applied, all chan-
nels in the multiplexer are turned off, and only a few
nanoamperes of leakage current will flow into the inputs. This
protects not only the multiplexer and the circuitry driven by the
multiplexer, but also protects the sensors or signal sources
which drive the multiplexer. All digital inputs have logic thresh-
olds of 0.8V and 2.4V, ensuring both TTL and CMOS compati-
bility without requiring pullup resistors. Break-before-make
operation is guaranteed. Power supply currents have been
reduced and typical power dissipation is less than 2 mW.

packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or a space
mission. In a GEO orbit, Rad-Pak provides true greater than
50 krad (Si) total radiation dose tolerance, dependent upon
space mission. This product is available with packaging and
screening up to Class S.

1. The value shown is the steady state value. The transient leakage is typically 10 A.
2. When the analog signal exceeds +13.5V or -12V the blocking action of the gate structure goes into operation. Only leakage cur-
rents flow and the channel on resistance rises to infinity.
3. Digital input leakage is primarily due to the clamp diodes. Typical leakage is less than 1 nA @ +25C.
4. Guaranteed by design.
5. Electrical characteristics, such as ON Resistance, will change when power supplies other than 15V are used.
