aip74hc/hct253
dual 4-input multiplexer; 3-state

the aip74hc/hct253 is a dual 4-bit multiplexer, each with four binary inputs (ni0 to ni3), an output enable input (noe()) and shared select inputs (s0 and s1). one of the four binary inputs is selected by the select inputs and routed to the output ny. a high on noe() causes the outputs to assume a high-impedance off-state. inputs include clamp diodes. this enables the use of current limiting resistors to interface inputs to voltages in excess of vcc.
