Output Low-Level Fixed Mode at Power On

To avoid malfunction at power on, this IC incorporates the following functions:

• All outputs are fixed to low level until VCC reaches more than 3 V.

• When VCC reaches 3 V (typ.), the internal logic depends on input signals.

• VCC must be more than 4.7 V for normal operation.
