ST3222EB

ST3222EC

± 15 kV ESD protected, 3 to 5.5 V

low power, up to 250 Kbps, RS-232 drivers and receivers

Features

■ ESD protection for RS-232 I/O pins ± 15 kV

human body model, ± 8 kV IEC 1000-4-2

contact discharge

■ 300 µA supply current

■ 250KBps minimum guarantee data rate

■ 6 V/µs minimum guarantee slew rate

■ Meet EIA/TIA-232 specification down to 3 V

■ Available in SSOP20 and TSSOP20

Description

The ST3222E is a 3 V 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 to ± 8 kV using IEC1000-4-2 Contact

Discharge and ±15 kV using the Human Body

Model. ST3222E has a proprietary low dropout

transmitter output stage providing true RS-232

performance from 3 to 5 V supplies with a dual

charge pump. The charge pump requires only four

small 0.1 mF external capacitors for operation

form 3 V supply. The device has two receivers and

two drivers. The ST3222E 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 Notebook, Sub-notebook

and Palmtop Computers, Battery Powered

Equipment, Hand-Held Equipment, Peripherals

and Printers.
