Detailed Description
Traditional fault-protected multiplexers constructed with three series switches. This produces good protection, limits switches input voltage range much below supply rails, reducing usable dynamic range. voltage side switch approaches within about either supply rail fault condition), switch impedance increases, limiting output signal range approximately less than appropriate polarity supply voltage. MAX4508/MAX4509 differ considerably from traditional fault-protected multiplexers, offering several advantages. First, they constructed with parallel FETs, allowing very resistance when switch Second, they allow signals pins that within beyond supply rails passed through switch terminal. This allows railto-rail signal operation. Third, when signal exceeds supply rails (i.e., fault condition), voltage COM_ limited supply rails. Operation identical both fault polarities.

Applications Information
Ground
There connection between analog signal paths GND. analog signal paths consist N-channel P-channel MOSFET with their sources drains paralleled their gates driven phase logic-level translators. power internal logic logic level translators input logic thresholds. logiclevel translators convert logic levels switched signals drive gates multiplexers. This drive signal only connection between power supplies analog signals. GND, COM_ have protection diodes
Transient Fault Condition
When fast rising falling transient exceeds output (COM_) follows input (NO_) supply rail with only nanoseconds delay. This delay switch on-resistance circuit capacitance ground. When input transient returns within supply rails, however, there longer output recovery time. positive faults, recovery time typically 2.5µs (see Typical Operating Characteristics). negative faults, recovery time typically 1.3µs. These values depend COM_ output resistance capacitance. delays depend fault amplitude. Higher COM_ output resistance capacitance increase recovery times.
Supply Current Reduction
When logic signals driven rail-to-rail from +15V -15V +15V, current consumption will reduced from 370µA (typ) 200µA.
