Reliably transmit data with our RS-232 transceivers
Increase system protection and data rates while lowering power consumption
Enhance RS-232 signaling reliability with our portfolio of transceivers with high-ESD protection. These integrated solutions feature wide voltage ranges down to 1.8 V and a variety of channel configurations and data rates for reliable communication in harsh environments.
High-ESD transceivers
Design for harsh environments and save board space using our RS-232 transceivers with integrated IEC-ESD 61000-4-2 support up to ±15-kV air-gap discharge, ±8-kV CDM and ±15-kV HBM.
High data rate transceivers
Optimize applications requiring data rates up to 1 Mbps using RS-232 transceivers with a wide range of channel configurations.
Low-voltage transceivers
Design for small battery-powered applications with RS-232 transceivers in QFN packages as small as 16 mm2 and compatible with 1.8-V processor interfaces.
