New analogue switch and multiplexer options

Siliconix incorporated has released two new high-reliability package options for the ‘L Series’ of low-voltage analogue switches and multiplexers.

Vishay Intertechnology subsidiary, Siliconix, has released two new high-reliability package options for the ‘L Series’ of low-voltage analogue switches and multiplexers.

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 Vishay Siliconix L Series are pin-and function-compatible companions to higher-voltage CMOS industry-standard analogue switches. They are also said to be industry’s first such low-voltage products built to MIL-STD-883.

Delivering faster, more accurate signal processing performance with lower power consumption, L Series analogue switches and multiplexers in the new CerDIP and LCC packages are intended for use in military and aerospace systems, including battery-powered equipment and communications. A -55 degrees C to +125 degrees C operating temperature range ensures reliable performance in rugged environments.

The high-bandwidth L Series devices include five monolithic quad SPST analogue switches (DG411L, DG412L, DG413L, DG441L, and DG442L), two single SPST analogue switches (DG417L and DG418L), a single SPDT analogue switch (DG419L), and two precision analogue multiplexers: the 8-channel DG408L and the dual 4-channel DG409L.

The devices’ DG-part-number nomenclature gives designers both the flexibility of a recognisable standard and the ability to choose the best part for a given application. A designer familiar with the DG409 for 12-V to 44-V applications may choose to incorporate the DG409L for 12-V down to 3-V applications.

Typical turn-on time for the L Series analogue switches is 20 ns – compared with up to 150 ns for industry-standard versions – while a 3-dB insertion loss at 280 MHz allows higher bandwidth operation. Providing the widest dynamic range with low signal errors and distortion, superior off-isolation performance of -71 dB at 50 MHz virtually eliminates crosstalk.

Allowing designers to take advantage of the power savings of lower supply voltages, devices in the L Series are specified for 2.7-V to 12-V single supplies or +/-3-V or +/-6-V dual-supply operation.

Samples and production quantities of L Series analogue switches and multiplexers in all four package types are available now, with lead times of eight weeks for larger orders.
