MAX4533 19-1452 Rev 1 10/99 Quad, Rail-to-Rail, Fault-Protected, SPDT Analog Switch General Description Features Rail-to-Rail Signal Handling The MAX4533 quad, single-pole/double-throw (SPDT), fault-protected analog switch is pin-compatible with the 40V Fault Protection with Power Off industry-standard MAX333 and MAX333A. The MAX4533 25V Fault Protection with 15V Supplies features fault-protected inputs and Rail-to-Rail signal All Switches Off with Power Off handling. The normally open (NO ) and normally closed (NC ) terminals are protected from overvoltage faults up No Power-Supply Sequencing Required During to 25V with power on and up to 40V with power off. Power-Up or Power-Down During a fault condition, NO and NC become high Output Clamped to Appropriate Supply Voltage impedance with only nanoamperes of leakage current During Fault ConditionNo Transition Glitch flowing to the source. In addition, the output (COM ) 1k (typ) Output Clamp Resistance During clamps to the appropriate polarity supply rail and pro- Overvoltage vides up to 10mA of load current. This ensures unam- biguous rail-to-rail outputs when a fault occurs. 175 (max) Signal Paths with 15V Supplies The MAX4533 operates from dual 4.5V to 18V power 20ns (typ) Fault Response Time supplies or a single +9V to +36V supply. All digital inputs 4.5V to 18V Dual Supplies have +0.8V and +2.4V logic thresholds, ensuring both +9V to +36V Single Supply TTL and CMOS logic compatibility when using 15V supplies or a +12V supply. On-resistance is 175 max Pin-Compatible with Industry-Standard and is matched between switches to 10 max. The off- MAX333/MAX333A leakage current is only 0.5nA at T = +25C and 10nA at A TTL/CMOS-Compatible Logic Inputs with 15V or T = +85C.

Signals on COM or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating. Note 2: NC and NO pins are fault protected. Signals on NC or NO exceeding -25V to +25V may damage the device. These limits apply with power applied to V+ or V-. The limit is 40V with V+ = V- = 0. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICSDual Supplies (V+ = +15V, V- = -15V, T = T to T , unless otherwise noted.
