SP3232EBEN-L產(chǎn)品概述
The SP3222EB/SP3232EB series is an RS-232 transceiver solution 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 0.1 μF capacitors in 3.3 V operation. This charge pump allows the SP3222EB/SP3232EB series to deliver true RS-232 performance from a single power supply ranging from +3.0 V to +5.5 V. The SP3222EB/SP3232EB are 2-driver/2-receiver devices. The ESD tolerance of the SP3222EB/SP3232EB devices is over ±15 kV for both Human Body Model and IEC61000-4-2 Air discharge test methods. The SP3222EB device has a low-power shutdown mode where the devices' driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1 μA.
