RS-232 Transceivers
RS-485 Transceivers


The 3PEAK RS232 transceivers are pin and spec compatible with popular industry standard devices for direct drop-in replacement or a reliable second source for high volume production. Our enhanced ESD (ElectroStatic Discharge) devices are suitable for rugged applications in harsh operating conditions; up to ±15kV IEC 61000-4-2, and ±15kV HBM (Human Body Model). On more recent RS-232 Transceiver chips, data rates of up to 1Mbps are achievable over shorter distances (up to 5 feet),and we also provide long distance RS-232 transceiver which could get over 50 feet.
