Description

   The Harris CD74HC157, CD74HCT157, CD74HC158 and CD74HCT158 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select input (S). The Enable input (E ) is active Low. When (E ) is High, all of the outputs in the 158, the inverting type, (1Y -4Y ) are forced High and in the 157, the noninverting type, all of the outputs (1Y -4Y ) are forced Low, regardless of all other input conditions.

   Moving data from two groups of registers to four common output busses is a common use of CD74HCT158. The state of the Select input determines the particular register from which the data comes. They can also be used as function generators.
