SP3222EB - MaxLinear

SP3222EB True +3.0V to +5.5V RS-232 Transceiver

The SP3222EB and SP3232EB series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or laptop computers. The SP3222EB / SP3232EB series has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222EB / SP3232EB series to deliver true RS-.
