The MAX243CSE+ is a +5V powered multichannel RS232 driver/receiver in 16 pin NSOIC 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 MAX243 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
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
