Beyond-the-rails mux and switch family simplifies power-supply requirements
Designers no longer need multiple switches/mux to switch both high- and low-voltage signals. Maxim’s beyond-the-rail technology helps simplify power-supply requirements and system design. Flexible and robust, the mux and switches are ideal 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.
In the past multiple devices were needed to mux/switch interface signals greater than 5 V for CAN, RS-485, and RS-232 interfaces, or to switch low-voltage signals less than 5 V for USB and audio signals. The ±25 V MAX14778 mux can multiplex up to 8 channels, making it an excellent choice for applications requiring connector sharing (multiplexing RS-232, USB, RS-485, CAN, or audio).
The ±25 V signal capability of all the devices enables switching of true RS-232 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 Full Speed USB (12 Mbps). The low 1.5 Ω (Max) RON and 3 mΩ (typical) RON flatness of the MAX14778 ensure precise voltage measurements over temperature ideal for precision analog input applications and connector sharing applications.
