The CD4512BC buffered 8-channel data selector is a complementary
MOS (CMOS) circuit constructed with N- and
P-channel enhancement mode transistors. This data selector
is primarily used as a digital signal multiplexer selecting
1 of 8 inputs and routing the signal to a 3-STATE output. A
high level at the Inhibit input forces a low level at the output.
A high level at the Output Enable (OE) input forces the
output into the 3-STATE condition. Low levels at both the
Inhibit and (OE) inputs allow normal operation.
Features

Wide supply voltage range: 3.0V to 15V

High noise immunity: 0.45 VDD (typ.)

3-STATE output

Low quiescent power dissipation:
0.25 μW/package (typ.) @ VCC = 5.0V
