Clarifications/Corrections to the Data
Sheet:
In the Device Data Sheet (DS30390E), the following
clarifications and corrections should be noted.

No.
No.
The specification for the High Voltage Open Drain
I/O (parameter D150, the RA4 pin) cannot be met
without possible long term reliability issues on that
I/O pin. If a high voltage drive is required, use an
external transistor that can support the required
voltage. The new value is shown in Table 1.
The minimum A/D reference voltage (parameter
A20) has been improved. The new value is shown
in Table 2.
