7.4 Layout

7.4.1 Layout Guidelines

For device reliability, the following common printed-circuit board layout guidelines are recommended.

• Bypass capacitors should be used on power supplies, and should be placed as close as possible to the VCCA,

VCCB pin and GND pin.

• Short trace lengths should be used to avoid excessive loading.

• PCB signal trace-lengths must be kept short enough so that the round-trip delay of any reflection is less than

the one shot duration, approximately 10ns, making sure that any reflection encounters low impedance at the

source driver.
