DESCRIPTION:
The IDT54/74FCT151T/AT/CT are high-speed 8-input multiplexers built using an advanced dual metal CMOS technology.
They select one bit of data from up to eight sources under the control of three select inputs.
Both assertion and negation outputs are provided.
The IDT54/74FCT151T/AT/CT has a common Active-LOW enable (E) input.
When E is LOW, data from one of eight inputs is routed to the complementary outputs according to the 3-bit code applied to the Select (S0-S2) inputs.
A common application of the ‘FCT151 is data routing from one of eight sources.
