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 non-inverting 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 buses is a common use of these devices. The state of the Select input determines the particular register from which the data comes. They can also be used as function generators. 14 15 16 9 13 12 11 10 1 2 3 4 5 7 6 8 S 1I0 1I1 1Y 2I0 2I1 GND 2Y VCC 4I0 4I1 4Y 3I0 3I1 3Y E Ordering Information PART NUMBER TEMP.
