NXP 74HC151D,653 芯片, 多路复用器, 8位, 8:1, SOIC-16
The 74HC151D is a 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 Y high. Inputs also include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
