Product Overview

The MAX250ESD+ is a +5V powered, isolated, RS232 driver/receiver in 14 pin NSOIC package. It is a chip set form the heart of a complete electronically isolated RS232 dual transmitter/receiver. By combining many functions on two chips, the cost and complexity required for an isolated digital interface is greatly reduced. Four low cost optocouplers, four capacitors, a diode and a small pot-core type transformer are all that are required to complete a 19.2k baud transceiver. Faster data rates are possible by using high-speed optocouplers. In addition to the driving and receiving circuitry for the optocouplers, the chip set includes a push-pull transformer driver to supply power to the interface's isolated side. This device is used in bridge ground differentials and data links to analogue circuits.
  • Supply voltage range is 4.5V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Isolated data interface
  • Shut down supply current is 100µA at TA=55°C to 125°C, maximum operating supply current is 0.5mA
  • Shutdown power is 5µW
  • 2 transmitters and 2 receivers
  • Switching frequency is 275KHz at TA=25°C
  • Maximum on- resistance power driver is 50 ohm at 25mA
