81840 128 Channel Multiplexer
High-performance 128-channel multiplexer features a typical 300 krad (Si) total dose tolerance
DDC’s 338 monolithic, CMOS analog multiplexer 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 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.
