| ST3232 3 TO 5.5V, LOW POWER, UP TO 400KBPS, RS-232 DRIVERS AND RECEIVERS s s s s s 300A SUPPLY CURRENT 300Kbps 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 AND TSSOP16 DIP SOP DESCRIPTION The ST3232 is a 3V powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements, high data-rate capabilities. ST3232 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5.5V supplies. The device requires only four small 0.1F standard external capacitors for operations from 3V supply. The ST3232 has two receivers and two drivers. The device is guaranteed to run at data rates of 250Kbps while maintaining RS-232 output levels. Typical applications are Notebook, Subnotebook and Palmtop Computers, Battery Powered Equipment, Hand-Held Equipment, Peripherals and Printers.
