Maxim 14778/14759/14764 switch range

Maxim has announced the MAX14778 (analog mux) and 14759-14764 (analog switches), ±25 V above- and below-the-rails devices that let the user switch/mux a wide signal range from standard 3 to 5.5 V supplies.

Designers no longer need multiple switches/mux to switch both high- and low-voltage signals. Beyond-the-rail technology helps simplify power-supply requirements and system design. Flexible and robust, the mux and switches are suitable for general-purpose system signal routing and industrial analog front-ends.

Specific applications include POS connector sharing, industrial analog inputs, handheld instrumentation, ATE and audio/data switching.

The ±25 V 14778 mux can multiplex up to eight channels, making it suitable for applications requiring connector sharing (multiplexing RS232, USB, RS485, CAN or audio).

The ±25 V signal capability of all the devices enables switching of true RS232 signals for connector sharing applications. For analog input applications, the wide voltage range provides a robust signal range to accommodate harsh industrial environments.

With a 75 MHz (min) bandwidth, they also switch fullspeed USB (12 Mbps). The low 1.5 Ω (Max) R_ON and 0.3 mΩ (typ) R_ON flatness of the 14778 ensure precise voltage measurements over temperature suitable for precision analog input applications and connector sharing applications.
