MAX4533EAP+

The MAX4533EAP+ is a quad, rail to rail, fault protected, SPDT analogue switch in 20 pin SSOP package. The MAX4533 features fault-protected inputs and rail to rail signal handling. The normally open (NO_ ) and normally closed (NC_ ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±40V with power off. During a fault condition, NO_ and NC_ become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output (COM_) clamps to the appropriate polarity supply rail and provides up to ±10mA of load current. This ensures unambiguous rail to rail outputs when a fault occurs. All digital inputs have +0.8V and +2.4V logic thresholds, it ensures both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175ohm max and is matched between switches to 10 ohm max. The off leakage current is only 0.5nA at TA = +25°C and 10nA at TA = +85°C.

• Supply voltage range is 9V to 36V, ±4.5V to ±18V
• Operating temperature range from -40°C to 85°C
• All switches off with power off
• No power supply sequencing required during power-up or power-down
• Output clamped to appropriate supply voltage during fault condition with no transition glitch
• 1Kohm (typ) output clamp resistance during overvoltage
• 20ns (typ) fault response time
• Pin compatible with industry standard MAX333/MAX333A
