DESCRIPTION:
• RAD-PAK® Technology hardened against
natural space radiation
• Total dose hardness >100 Krads (Si),
dependent upon orbit
• Package:
-16 Pin RAID-PAK® flat pack
• On-resistance, <400 Ohms max
• Transition time, <500ns
• On-resistance match, <10 Ohms
• NO-Off leakage current, <20pA at 25oC
• 1.5pC charge injection
• Single-supply operation (4.5V to 30V)
bipolar-supply operation (±4.5V to
±20V)
• Plug-in upgrade for industry-standard
DG508A/DG509A
• Rail-to-rail signal handling
• TTL/CMOS-logic compatible
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 guaranteed low charge injection (1.5pC typ) and electrostatic 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 specified temperature range and over the ±4.5V to
±18V supply range. Capable of surviving
space environments, the 338 is ideal for satellite, spacecraft, and space probe missions.
The patented radiation-hardened RAD-PAK®
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.

1. The algebraic convention where the most negative value is a minimum and the most positive value a
maximum is used in this data sheet.
2. Characterized and not 100% tested.
3. DRON = RON(MAX) - RON(MIN).
4. Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed at 25 oC.
5. Guaranteed by design.
6. Worst-case isolation is on channel 4 because of its proximity to the drain pin. Isolation = 20logVCOM/VNO,
where VCOM = output and VNO = input to off switch.
