Интерфейс RS-232 MAX234CWE+

RS232 драйвер / приемник RS232 , 4.5В-5.5В питание, 4 драйвера, WSOIC-16

The MAX234CWE+ is a +5V powered, multichannel RS232 driver in 16 pin WSOIC package. The line driver is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces particularly applications where ±12V is not available. It eliminates need of external components and is recommended for applications where printed circuit board space is critical. It has dual internal charge pump that convert +5V to ±10V (unloaded) for RS232 driver operation. The first converter uses capacitor C1 to double the +5V input to +10V on C3 at the V+ output. The second converter uses capacitor C2 to invert +10V to -10V on C4 at the V- output. Typical applications include interface and portable diagnostics equipment.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from 0°C to 70°C
• Eliminates the need for a bipolar ±12V supply
• Four transmitters
• Four external capacitors of 1µF
• Data rate of 120Kbps
