PRELIMINARY
Notice. This is not a final specification.
Some parametric limits are subject to change.
Application Circuit Example
Note how to use this IC
Power-on Reset
Input signal with sufficient low impedance to input terminal.
The capacitance of output terminal as small as possible.
Set the capacitance between Vcc and GND near the pins if possible.
Assign an area as large as possible for grounding.
VCC
The M52791 has an intermal power-on reset function that sets each
control r egister to "0" during IC power ON.
The power-on reset VTH has 2.5V.
