CD4512 - National Semiconductor

CD4512 8-Channel Buffered Data Selector

The CD4512BM 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 TRISTATE output A high level at the Inhibit input forces a low level at the output .
