SP3232EUCN-L產(chǎn)品概述
The SP3222EU and the SP3232EU are 2 driver, 2 receiver RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. Their data transmission rate of 1000 kbps meets the demands of high speed RS-232 applications. The SP3222EU/SP3232EU 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 SP3222EU/SP3232EU series to deliver true RS-232 performance from a single power supply ranging from +3.0 V to +5.5 V. The ESD tolerance of the SP3222EU/SP3232EU devices are over
±15 kV for both Human Body Model and IEC61000-4-2 Air discharge test methods. The SP3222EU 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.
Features:
Meets true EIA/TIA-232-F Standards from a +3.0 V to +5.5 V power supply
Minimum 1000 kbps Data Rate
1 μA Low Power Shutdown with Receivers active (SP3222EU)
Interoperable with RS-232 down to a +2.7 V power source
Enhanced ESD Specifications:
+15 kV Human Body Model
+15 kV IEC61000-4-2 Air Discharge
+8 kV IEC61000-4-2 Contact Discharge
Ideal for Handheld, Battery Operated Applications
