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.
