| ST3384E 15KV ESD-PROTECTED, 3 TO 5.5V, LOW POWER, UP TO 250KBPS, RS-232 TRANSCEIVER s s s s s s s s s ESD PROTECTIO FOR RS-232 I/O PINS 15KV (HUMAN BODY MODEL) LATCHUP FREE 1A LOW POWER SHUTDOWN 300A SUPPLY CURRENT 250Kbps GUARENTEED DATA RATE 20s TYPICAL TIME TO EXIT SHUTDOWN 6V/s GUARANTEED SLEW RATE MEET EIA/TIA-232 SPECIFICATIONS DOWN TO 3V PACKAGES: SO-18 AND SSOP-20 SO-18 SSOP20 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 0.1F external capacitors for operation from a 3.3V supply. ORDERING CODES Type ST3384ECD ST3384EBD ST3384ECDR ST3384EBDR ST3384ECPR ST3384EBPR Temperature Range 0 to 70 C -40 to 85 C 0 to 70 C -40 to 85 C 0 to 70 C -40 to 85 C Package 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 1A 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.
