Maxim Integrated (MAX249CQH+D) Transceiver RS232, 4.5V-5.5V supply

Product Overview The MAX249CQH+D is a +5V powered multichannel RS232 driver/receiver in 44 pin PLCC 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 MAX249 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 Six RS232 drivers and ten RS232 receivers Saves board space 5µW shutdown mode saves power for reduced power requirements Data rate of 120Kbps VCC supply current of 11mA with no load and 57mA with 3Kohm loads on all outputs Transition slew rate is 10V/µs (CL = 50pF to 2500pF, RL = 3Kohm to 7Kohm) Shutdown supply current of 8µA at TA = 25°C Applications Communications & Networking, Portable Devices, Medical Product Information Device Type: Transceiver IC Interface Type: RS232 No. of Drivers: 6Drivers No. of Receivers: 10Receivers Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Driver Case Style: PLCC No. of Pins: 44Pins Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - Automotive Qualification Standard: - MSL: MSL 3 - 168 hours IC Generic Number: MAX249
