Table 1 - Differences between the MT88E43A and MT88E43B
Introduction
This application sheet compares the MT88E43B
data sheet specification with that of the MT88E43A.
The MT88E43B is pin to pin compatible with the
MT88E43A. Systems currently using the MT88E43A
should be able to accept the MT88E43B with no
modifications to their existing hardware and
software.
Consult
consequences of substituting devices in your
application.

the
Table 1 illustrates the differences between the two
devices. For full details on the MT88E43B, refer to
the MT88E43B data sheet.
