The MAX4533CWP+ is a quad, rail to rail, fault protected, SPDT analogue switch in 20 pin WSOIC 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 0°C to 70°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
