1. General description

The 74HC251; 74HCT251 is an 8-bit multiplexer with eight binary inputs (I0 to I7), three select

inputs (S0 to S2) and an output enable input (OE). The select inputs select one of the eight binary

inputs and route it to the complementary outputs (Y and Y). A HIGH on OE causes the outputs to

assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current

limiting resistors to interface inputs to voltages in excess of VCC.

2. Features and benefits
