CY74FCT157T QUAD 2-INPUT MULTIPLEXERS

NC – No internal connection The ’FCT157T devices are quad two-input multiplexers that select four bits of data from two sources under the control of a common data-select (S) input. The output-enable (E) input is active low. When E is high, all of the outputs (Y) are forced low, regardless of all other input conditions. Moving data from two groups of regist.

  – No internal connection The ’FCT157T devices are quad two-input multiplexers that select four bits of data from two sources under the control of a common data-select (S) input. The output-enable (E) input is active low. When E is high, all of the outputs (Y) are forced low, regardless of all other input conditions. Moving data from two groups of registers to four common output buses is a common use of the ’FCT157T devices. The state of S determines the particular register from which the data com.
