All are ideal for puter peripherals, point-of-sale equipment, consumer and embedded applications. These devices use 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 it to deliver pliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. At voltages between 2.7V and 3.0V the driver outputs are pliant with RS-562 and can interface to RS-232 over short cables. The Auto On-line® Plus feature allows the device to...
