TYPICAL APPLICATIONS
Figure 13 shows a typical application for the LTC1344
using the LTC1343 mixed mode transceiver chip to gener-
ate the clock and data signals for a serial interface. The

LATCH are shared by both chips. Each driver output and
receiver input is connected to one of the LTC1344 termi-
nation ports. Each electrical protocol can then be chosen
using the digital select lines.
