ST3222B:3 TO 3.6V, LOW POWER, UP TO 400 KBPS RS-232 DRIVERS AND RECEIVERS, [-40oC, 85oC] TEMPERATURE RANGE

The ST3222 is a 3 V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements and high data-rate capabilities. ST3222 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 3.6 V power supplies. The device requires only four small 0.1 mF standard external capacitors for operating from 3 V supply. The ST3222 has two receivers and two drivers. The ST3222 features a 1 mA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers can remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1 mA supply current. The device is guaranteed to run at data rates of 250 Kbps while maintaining RS-232 output levels. Typical applications are notebooks, sub-notebooks and palmtop computers, battery powered equipment, hand-held equipment, peripherals and printers.
