Features  
Description  
• ’AC257, ’ACT257. . . . . . . . . . . . . Non-Inverting Outputs The ’AC257, ’ACT257 and CD74ACT258 are quad 2-input  
multiplexers with three-state outputs that utilize Advanced  
CMOS Logic technology. Each of these devices selects four

bits of data from two sources under the control of a common  
Select input (S). The Output Enable (OE) is active LOW.  
When OE is HIGH, all of the outputs (Y or Y) are in the high-  
impedance state regardless of all other input conditions.

Moving data from two groups of registers to four common  
output buses is a common use of the ’AC257, ’ACT257, and  
CD74ACT258. The state of the Select input determines the  
particular register from which the data comes. The ’AC257,  
’ACT257 and CD74ACT258 can also be used as function  
generators.
