Vishay released a trio of low-voltage monolithic CMOS analog switching ICs for 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 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 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 devices offer the advantage of bi-directional signal, rail-to-rail analog signal handling. 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.
