Applications Information
AC Components on VGG
When the ground difference voltage, VGG, has a time
varying (AC) component, limit the amplitude to ensure
that the MAX14842 operates as specified. The maximum
allowable amplitude of an AC signal on VGG is a function
of frequency.
Power-Supply Sequencing
The MAX14842 does not require power-supply sequenc-
ing. The logic levels are set independently on either side
by VDDA and VDDB. Each supply can be present over
the entire specified range regardless of the level or pres-
ence of the other.
Power-Supply Decoupling
To reduce ripple and the chance of introducing data
errors, bypass VDDA and VDDB with 0.1FF ceramic
capacitors to GNDA and GNDB, respectively. Place the
bypass capacitors as close to the power-supply input
pins as possible.
Unidirectional and Bidirectional Level
Translator
The MAX14842 operates both as a unidirectional device
and bidirectional device simultaneously. Each unidirec-
tional channel can only be used in the direction shown
in the Functional Diagram. The bidirectional channels
function without requiring a direction input.
PROCESS: BiCMOS
