Maxwell Technologies’ 338 monolithic, CMOS
analog multiplexer features the 338 is
designed to connect one of eight inputs to a
common output by control of a 3-bit binary
address, and may be used as either a mux or
a demux. On-resistance is 400 ohms max,
and the it conducts current equally well in both
directions. These muxes feature extremely
low off leakages (less than 20pA at 25°C), and
extremely low on-channel leakages (less than
50pA at 25°C). The new design offers guaran-
teed low charge injection (1.5pC typ) and elec-
trostatic discharge (ESD) protection greater
than 2000V, per method 3015.7. The 338
operates from a single 4.5V to 30V supply or
from dual supplies of ±4.5V to ±20V. All control
inputs (whether address or enable) are TTL
compatible (0.8V to 2.4V) over the full speci-
fied temperature range and over the ±4.5V to
±18V supply range. Capable of surviving
space environments, the 338 is ideal for satel-
lite, spacecraft, and space probe missions.
The patented radiation-hardened

technology incorporates radiation shielding in
the microcircuit package. It eliminates box
shielding while providing required lifetime in
orbit. This product is available up to Class S
packaging and screening.
