Exar offers a large portfolio of RS-232 serial transceivers. The family consists of traditional RS-232 transceivers to the more advanced RS-232 transceivers with Auto On-line Plus and low voltage logic (1.65V to 5.5V I/O logic supply) features. In addition, many of the RS-232 transceivers have enhanced ESD protection. Exar offers new RS-232 products that meet rigid IEC 61000-4-2 air-gap and contact ESD standards. This protection makes the product immune to damage from ESD strikes. Many of the devices are drop-in replacements and functional equivalents to existing industry standard solutions.
