106, 114, 130,
138, 146, 154
Supply voltage. VCC is the 3.3-V (with respect to GND) supply for the functional logic
gates.
VCC(5V)
8, 21, 54, 80,
108, 134
8, 19, 50, 72,
98, 122
Supply voltage. VCC(5 V) is the 5-V secondary supply voltage for the clamp diodes of
5-V tolerant input and output buffers. The clamp diodes provide protection for the
buffers in a 5-V switching environment.
