MAX14569 19-5523 Rev 0 9/10 Dual-Pair LLT with Charge Pump and High-ESD Protection General Description Features The MAX14569 is a dedicated dual-pair unidirectional S Ultra-Low Shutdown Supply Current, 0.01A (typ) logic-level translator that is ideal for industrial and meter- S Ultra-Low V Supply Current, 1A (max) L ing applications. Voltages V and V set the logic CC L S Operates Down to 1.6V on V L levels on either side of the device. Logic-high signals S Continuous Current Drive Capability > 10mA present on the V side of the device appear as high- L voltage logic signals on the V side of the device and CC S Extended ESD Protection on V Input and CC vice versa. Output Lines 25kV Human Body Model The device has two pairs of logic-level translators in back-to-back configuration: one logic-level translator 15kV IEC 61000-4-2 Air-Gap Discharge 12kV IEC 61000-4-2 Contact Discharge from a low voltage to a high voltage and the other logic- level translator from a high voltage to a low voltage. The S 16-Pin QSOP Package device also features a high-efficiency charge pump to S -40NC to +85NC Extended Operating Temperature boost the battery input, V , to V (5V). BAT CC Range The device features an extreme power-saving mode Applications that reduces supply current to a typical 0.01FA. The device also features thermal short-circuit protection for Automatic Meter Reader enhanced protection in applications that route signals Remote Communications System externally. Industrial Networking In addition, the device features enhanced high electro- static discharge (ESD) Human Body Model (HBM) pro- Ordering Information tection on OUTAVCC, INBVCC, OUTCVCC, and INDVCC ports up to Q25kV. The MAX14569 is available in a PART TEMP RANGE PIN-PACKAGE 16-pin QSOP package, and is specified over the -40NC MAX14569EEE+T -40NC to +85NC 16 QSOP to +85NC extended temperature range. +Denotes a lead(Pb)-free/RoHS-compliant package.

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.
