New Vishay Siliconix Analog Switches/Multiplexers Operate Over Wide Voltage Range of 2.7 V to 12 V for Single Supply or ±2.7 V to ±6 V for Dual Supply

MALVERN, PA — Jan. 16, 2006 — Vishay Intertechnology, Inc. (NYSE: VSH), today released a trio of precision low-voltage monolithic CMOS analog switching ICs that combine a wide voltage range, low leakage, and tight on-resistance matching for precision signal switching and routing.

Released today were an 8-channel analog multiplexer (DG9051), a dual 4-channel analog multiplexer (DG9052), and a triple 2-channel single-pole/double-throw (SPDT) analog switch (DG9053). The new devices are intended for use in end products including cell phones, communication systems, modems, data acquisition systems, automated test equipment, and automotive systems.

All three devices feature a wide input voltage range of 2.7 V to 12 V for single-supply implementations and ±2.7 V to ±6 V for dual-supply implementations. Built on Vishay’s proprietary high-density process, the new devices offer the advantage of bi-directional signal, rail-to-rail analog signal handling. These characteristics, along with the wide voltage range, offer significant flexibility to circuit designers

The CMOS logic compatible control inputs of the DG9051, DG9052, and DG9053 have guaranteed 2-V logic high/0.8-V logic low when operating from a single 5-V or dual ±5-V power supplies, and 2.4-V logic high/0.8-V logic low with V + = 12 V power supplies. On-resistance ranges as low as 30 ohms depending on the power supply configuration, with guaranteed low on-resistance matching as low as 5 ohms.

Packaged in the TSSOP-16 case, the devices have lead (Pb)-free terminations and are pin-compatible with 74HC4051/2/5. They operate over a temperature range of –40 °C to +85 °C.

Samples and production quantities of the new analog switches/multiplexers are available now, with lead times of six to eight weeks for larger orders.
