Siliconix Debuts L Series Switches and Multiplexers

July 06, 2005 by Paul Shepard

Siliconix Inc. (Santa Clara, CA), a subsidiary of Vishay Intertechnology Inc. (Malvern, PA), announced two new high-reliability package options for the L Series of low-voltage analog switches and multiplexers. The L Series switches and multiplexers are intended for use in military and aerospace systems, including battery-powered equipment and communications. A –55°C to +125°C operating temperature range ensures reliable performance in rugged environments.

The L Series devices include five monolithic quad SPST analog switches (DG411L, DG412L, DG413L, DG441L and DG442L), two single SPST analog switches (DG417L and DG418L), a single SPDT analog switch (DG419L), and two precision analog multiplexers (the eight-channel DG408L and the dual four-channel DG409L). The L Series features a typical turn-on time of 20ns; a 3dB insertion loss at 280MHz; an off-isolation performance of -71dB at 50MHz; a maximum on-resistance of 29 ohms from 100 ohms; a typical transition time of 30ns from 160ns, a turn-on time of 38ns from 115ns; off-isolation of -70dB at 1MHz; and ESD protection to 2,000V.

Now available in both the CerDIP and 20 pin LCC packages, as well as in the narrow-body SOIC 16 and TSSOP 16, devices in the L Series are pin-compatible and function-compatible companions to higher-voltage CMOS industry-standard analog switches, and are built to MIL-STD-883. Samples and production quantities of the L Series analog switches and multiplexers in all four package types are available now, with lead times of eight weeks for larger orders. Pricing in 1,000-piece quantities for US delivery starts at $2.50.
