SP3232E True 3.0V to 5.5V RS-232 Transceivers
1、芯片描述:
The SP3222E and SP3232E series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222E / SP3232E series has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222E / SP3232E series to deliver true RS-232 performance from a single power supply ranging from 3.0V to 5.5V. The SP3222E / SP3232E are 2-driver / 2-receiver devices. This series is ideal for portable or hand-held applications such as notebook or palmtop computers. The ESD tolerance of the SP3222E / SP3232E devices are over ±15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods. The SP3222E 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 1µ(点击咨询);A
