ST3232E 15KV ESD-PROTECTED, 3 TO 5.5V, LOW POWER, UP TO 250KBPS, RS-232 DRIVERS AND RECEIVERS s s s s s s ESD PROTECTIO FOR RS-232 I/O PINS 15KV HUMAN BODY MODEL 8KV IEC 1000-4-2 CONTACT DISCHARGE 300A SUPPLY CURRENT 250Kbps MINIMUM GUARENTEED DATA RATE 6V/s MINIMUM GUARANTEED SLEW RATE MEET EIA/TIA-232 SPECIFICATIONS DOWN TO 3V AVAILABLE IN DIP-16, SO-16, SO-16 LARGE SSOP16 AND TSSOP16 DIP SOP DESCRIPTION The ST3232E is a 3V powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements, high data-rate capabilities and enhanced electrostatic discharge (ESD) protection to 8kV using IEC1000-4-2 Contact Discharge and 15kV using the Human Body Model. ST3232E has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5V supplies witha a dual charge pump. The charge pump requires only four small 0.1F standard external capacitors for operations from 3V supply. The ST3232E has two receivers and two drivers.
