DESCRIPTION
The A3232 consists of two line drivers, two line
receivers, and a dual charge-pump circuit with ±12kV
ESD protection termina to terminal.

The A3232 meets the requirements of TIA/EIA-232-F
and provides the electrical interface between an
asynchronous communication controller and the
serial-port connector.

The charge pump and four small external capacitors
allow operation from a single 3V to 5.5V supply. The
A3232 operates at data signaling rates up to 250
kbps.

The A3232 is available in SOP16 and TSSOP16
package.
