CD4512BMCD4512BC 8-Channel Buffered Data Selector

General Description

The CD4512BMCD4512BC 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
