Products Detail

The SP3243E series is a 3-driver/5-receiver RS-232 transceiver designed for portable or hand-held applications. It operates from a single +3.0V to +5.5V power supply and features an internal charge pump that generates ±5.5V RS-232 voltage levels. The devices include AUTO ON-LINE® circuitry that automatically wakes up from a 1µA shutdown when an RS-232 cable is connected and a peripheral is turned on. The series offers slew-rate limited outputs for reduced crosstalk and EMI, and enhanced ESD specifications (±15kV HBM, ±15kV IEC61000-4-2 Air Discharge, ±8kV IEC61000-4-2 Contact Discharge). The 'U' and 'H' series are optimized for high speed with data rates up to 1Mbps. The charge pump requires only 0.1µF capacitors for 3.3V operation. The devices are available in lead-free packaging.
