SP3232EB
Description
The SP3222EB and SP3232EB series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or laptop puters. 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-232 performance from a single power supply ranging from 3.0V to 5.5V. The SP3222EB / SP3232EB are 2-driver / 2-receiver devices. The ESD tolerance of the SP3222EB / SP3232E devices is over ±15k V 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 1µA.
Features
- Meets true EIA / TIA-232-F standards from a 3.0V to
5.5V power supply
