Description

The TPT3232E is IEC61000 ESD protected, 3.0V to

5.5V powered transceivers that meet the RS-232

standards for balanced communication. Each receiver

converts TIA/RS-232 inputs to TTL/CMOS levels.

The devices have a typical threshold of 1.25V, a typical

hysteresis of 0.3V, and can accept ±15V inputs. The

device operates at data signaling rates up to 250 kbps.

The TPT3232E is available in SOP16, SSOP16 and

TSSOP16 package, and is characterized from –40°C

to 125°C.
