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.
