Multiplexers operate over wide voltage range

Malvern, Pa. — Vishay Intertechnology, Inc. released a trio of low-voltage, monolithic CMOS analog switches that are said to combine a wide voltage range, low leakage, and tight on-resistance matching for precision signal switching and routing.

Released 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 switches are intended for use in cell phones, communication systems, modems, data acquisition systems, automated test equipment, and automotive applications.

All three switches feature a wide input voltage range of 2.7 volts 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 multiplexers offer the advantage of bi-directional signal and rail-to-rail analog signal handling. These characteristics, along with the wide voltage range, offer significant flexibility to circuit designers, according to Vishay.

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-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 analog switches/multiplexers are available now. Pricing for U.S. delivery in 1,000-piece quantities is 86 cents each. Click here for the DG9051, DG9052, DG9053 data sheets.
