1/11May 2002 ESD PROTECTIO FOR RS-232 I/O PINS
±15KV HUMAN BODY MODEL
±8KV IEC 1000-4-2 CONTACT DISCHARGE 300μA SUPPLY CURRENT 250Kbps MINIMUM GUARENTEED DATA
RATE 6V/μs MINIMUM GUARANTEED SLEW RATE MEET EIA/TIA-232 SPECIFICATIONS DOWN
TO 3V AVAILABLE IN DIP-16, SO-16, SO-16 LARGE
AND TSSOP16
DESCRIPTIONThe ST3232E is a 3V powered EIA/TIA-232 and
V.28/V.24 communication interfaces with low
power requirements, high data-rate capabilities
and enhanced electrostatic discharge (ESD)
protection to ±8kV using IEC1000-4-2 Contact
Discharge and ±15kV using the Human Body
Model. ST3232E has a proprietary low dropout
transmitter output stage providing true RS-232
performance from 3 to 5V supplies witha a dual
charge pump. The charge pump requires only four
small 0.1μF standard external capacitors for
operations from 3V supply.
The ST3232E 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.

PIN CONFIGURATION
PIN DESCRIPTION
ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied. V+ and V- can have a maximum magnitude of +7V, but their absolute addition can not exceed 13 V.
