74HC151 Datasheet PDF - NXP

General description

●The 74HC151; 74HCT151 are 8-bit multiplexer with eight binary inputs (I0 to I7), three select inputs (S0 to S2) and an enable input (E). One of the eight binary inputs is selected by the select inputs and routed to the complementary outputs (Y and Y). A HIGH on E forces the output Y LOW and output YHIGH. Inputs also include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
