Интерфейс RS-232 MAX242CPN+

Приемопередатчик RS232 , 4.5В-5.5В питание, 2 драйвера, DIP-18

The MAX242CPN+ is a +5V powered multichannel RS232 driver/receiver in 18 pin DIP package. This device is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces. It is particularly suitable for applications where ±12V is not available. The MAX242 has four sections such as dual charge pump DC to DC voltage converter, RS232 driver, RS232 receiver and receiver/transmitter enable control inputs. The integrated charge pump circuitry eliminates the need for bipolar ±12V supply and enables single supply operation from +5V supply. It is used in interface translation and multidrop RS232 network applications.

• Supply voltage range from 4.5V to 5.5V
• Operating temperature range from 0°C to 70°C
• Two RS232 drivers and two RS232 receivers
• Saves board space
• 5µW shutdown mode saves power for reduced power requirements
• Data rate of 200Kbps
• Transition slew rate is 12V
• µs (CL = 50pF to 2500pF, RL = 3Kohm to 7Kohm)
• VCC supply current (VSHDN = VCC) of 4mA with no load and 15mA with 3Kohm load at both inputs
• Shutdown supply current of 0.1µA at TA = 25°C

• Separate shutdown and enable
