SAN DIEGO -- Space Electronics Inc. here has introduced new 64- and 128-bit multichip module (MCM) channel analog multiplexers featuring radiation-tolerance-enhancing packaging technology
The company said this technology is a cost-effective alternative to specialty components designed specifically for space applications.
Through the company's Rad-Pak technology, the MCM channel analog multiplexers can be made total-dose-tolerant to varying levels, depending on the orbits they travel, said Stuart Shanken, director of sales and marketing for Space Electronics, a subsidiary of Maxwell Technologies.
"These components allow spacecraft design enginers the price and technology advantages of commercial components while providing radiation shielding in the microcircuit package," said Shanken.
The radiation-enhanced version MCM version has100 Krad (si) total-dose tolerance, while the radiation-hard version can provide 300- Krad to 1 Mrad tolerance. Both are available with packaging and screening up to MCM Class K.
In addition, both multiplexers offer low constant on-resistance, and do not suffer from latchup or static discharge blowout. Their digital inputs are designed to operate from both TTL and CMOS levels, without the need for pull-up resistors. They are fault-protected and provide high isolation during power-out.
The 63- and 128-bit channel multiplexers are priced at $5,695, and $8,500, respectively, for Class H devices in quantities of 25. Class K pricing was not available.
