LTC1321/LTC1322/LTC1335
TYPICAL APPLICATI S
A typical EIA562/RS232 interface application is shown in
Figure 17 with LTC1322. A typical EIA562 interface appli-
cation with LTC1335 is shown in Figure 18.
A typical connection for RS485 transceiver is shown in
Figure 19. A twisted pair of wires connects up to 32 drivers
and receivers for half duplex multi-point data transmis-
sion. The wires must be terminated at both ends with
resistors equal to the wire’s characteristic impedance,
generally 120Ω. An optional shield around the twisted pair
helps to reduce unwanted noise and should be connected
to ground at one end.
