CD4512BC
8-Channel Buffered Data Selector
General Description
The CD4512BC buffered 8-channel data selector is a com-
plementary MOS (CMOS) circuit constructed with N- and
P-channel enhancement mode transistors. This data selec-
tor 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 out-
put. 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
s Wide supply voltage range: 3.0V to 15V
s High noise immunity: 0.45 V_DD (typ.)
s 3-STATE output
s Low quiescent power dissipation:
0.25 µW/package (typ.) @ V_CC = 5.0V
s Plug-in replacement for Motorola MC14512
