SP3239E中文资料Intelligent +3.0V to +5.5V RS-232 Transceiver数据手册MaxLinear规格书

描述 Description

The SP3239E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers. The SP3239E uses an internal high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3239E device to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.0V. The SP3239E is a 5-driver/3-receiver device, ideal for laptop/notebook computer and PDA applications. The SP3239E includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown.For technical support or help choosing a product please email Exar’s Serial Technical Support group at: serialtechsupport@exar.com.
