Power-Supply Bypassing and Layout
The MAX7440/MAX7441/MAX7442 operate from a sin-
gle +5V supply. Bypass V
CC
to GND with a 0.1µF and
1µF capacitor. These capacitors filter all frequencies
over 1MHz. Place all external components as close to
the devices as possible. To maintain good crosstalk
performance ensure that input and output lines do not
run parallel for any distance. If it is necessary to have
parallel lines, run a ground trace in between each line.
Refer to the MAX7440 Evaluation Kit for a proven PC
board layout example.
