Figure 1. MAX1448 EV Kit Schematic

Output Buffer/Driver

The SN74ALVCH16244 buffer/driver buffers the

MAX1448’s digital output, which produces straight offset

binary data. The buffer is able to drive capacitive loads,

which may be present at the logic analyzer connection,

without compromising the digital output signal. The out-

puts of the buffer are connected to a 40-pin header (J1)

located on the right side of the EV kit where the user can

connect a logic analyzer or data-acquisition system.
