Nexperia 74HC251D,653 Multiplexer / 1821899

When simplifying interface buses, we make your choice simple By enabling input expansion, digital multiplexers can simplify interface buses. Our devices cover a wide range of options to suit your particular needs. They feature low propagation delay and high noise immunity, while ensuring minimal power consumption.Mixed 5 V and 3.3 V applications Bus width reduction High noise immunity Low power consumption Wide supply voltage range Low propagation delay Over voltage tolerant input options Complementary output optionsThe 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.Input levels: For 74HC251: CMOS level For 74HCT251: TTL level Low-power dissipation Non-inverting data path Multiple package options Specified from -40 °C to +85 °C and from -40 °C to +125 °C
