ИС аналогового переключателя MAX4711EUE+T

Аналоговый переключатель , с защитой от неисправностей, 4 канал(-ов), SPST - NC, 25 Ом

The MAX4711EUE+T from Maxim Integrated Products is a fault protected, low voltage, quad SPST analogue switch in 16 pin TSSOP package. Due to fault protection feature the analogue switch input (NO_ or NC_) and output (COM_) pins are not symmetrical. This feature allows for analogue input to go beyond plus or minus supplies without device drawing excessive amounts of current from analogue inputs. When analogue inputs are driven beyond supply rails when switch is on, it will sense a fault and turn itself off and analogue switch output will be clamped to same polarity supply as input signal and will not go beyond supply rails. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±4.5V to ±5.5V or single +4.5V to +11V supplies. Applications include communication, battery operated systems, signal routing, test equipments, data acquisition, industrial and process control, avionics, redundant/back-up systems.

• Four normally closed switches (NO), rail to rail signal handling
• Switching times are less than 125ns for tON and less than 80ns for tOFF
• Operate from a single +2.7V to +11V supply or from dual ±2.7V to ±5.5V supplies
• ±12V fault protection with power off, ±7V fault protection with ±5V supplies
• 12V and -7V fault protection with +5V supply, +12V and -9V fault protection with +3V supply
• Fault protected digital inputs exceed V+ supply rail, 5ohm on-resistance flatness (5V single supply)
• All switches off with power off, pin compatible with industry standard MAX391
• Output clamped to appropriate supply voltages during fault condition
• 40 ohm maximum on-resistance, 2 ohm on-resistance match between channels at +5V single supply
• Operating temperature range from -40°C to +85°C
