Nexperia 74HC251D,653 Multiplexer

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
Overvoltage tolerant input options
Complementary output options

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.

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

For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
