1 / 11 page 1/11 July 2003 s ESD PROTECTIO FOR RS-232 I/O PINS ±15KV (HUMAN BODY MODEL) s LATCHUP FREE s 1µA LOW POWER SHUTDOWN s 300 µA SUPPLY CURRENT s 250Kbps GUARENTEED DATA RATE s 20 µs TYPICAL TIME TO EXIT SHUTDOWN s 6V/µs GUARANTEED SLEW RATE s MEET EIA/TIA-232 SPECIFICATIONS DOWN TO 3V s PACKAGES: SO-18 AND SSOP-20 DESCRIPTION The ST3384E is a 3V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements, high data-rate capabilities and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model. The ST3384E has a proprietary low dropout transmitter output stage enabling true RS-232 performance from 3 to 5.5V supplies with a dual charge pump. The charge pump require only four small 0.1µF external capacitors for operation from a 3.3V supply. The device is guaranteed to run at data rates of 250Kbps while maintaining RS-232 output levels. The ST3384E has two receivers and two drivers. It features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Typical applications are in Notebook, Sub-notebook, and Palmtop Computers, Battery Powered Equipment, Hand-Held Equipment, Peripherals, Printers.
