DC1851A

DC1851A demonstration circuit 1851A showcases the LTC®2872 RS232/RS485 dual multiprotocol transceiver with integrated termination. Separate supply inputs power the interface and logic sections, permitting operation of the logic control and I/O down to 1.7V. LEDs indicate when supplies are present. Control pins are accessible via turrets for external connections, or they may be set high or low by means of a jumper. All logic I/O and interface I/O is routed to turrets. The RS485 interface lines are also available at a terminal block for convenient connection of a transmission line. Because the LTC2872 contains half-/ full-duplex switching, it is unnecessary to jumper A and B to Y and Z for half-duplex operation.

• Input supply range from 3 to 5.5V at VCC operating
• 500Kbps min value of maximum data rate RS232 and 20Mbps min value of maximum data rate RS485
