HEF4512B - NXP

HEF4512B 8-input multiplexer with 3-state output

The HEF4512B is an 8-input multiplexer with 8 binary inputs (I0 to I7), an enable input (E) and an output enable input (EO). One of eight binary inputs is selected by select inputs S0, S1 and S2, and is routed to the output O. A HIGH on EO causes O to assume a high impedance OFF-state, regardless of other input conditions. This allows the output HEF4512B MS.
