DESCRIPTION
Demonstration circuit 1851A showcases the LTC
®
2872
RS232/RS485 dual multiprotocol transceiver with inte-
grated 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 tur-
rets 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.
