CD4512BM CD4512BC 8-Channel Buffered Data Selector
General Description
The CD4512BM CD4512BC buffered 8-channel data selec-
tor 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 TRI-
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 TRI-STATE condition Low
levels at both the Inhibit and (OE) inputs allow normal oper-
ation
