Features  
Description  
• CD74AC257, CD74ACT257 . . . . Non-Inverting Outputs The CD74AC257, CD74ACT257 and CD74ACT258 are  
quad 2-input multiplexers with three-state outputs that utilize  
the Harris Advanced CMOS Logic technology. Each of these  
• CD74ACT258 . . . . . . . . . . . . . . . . . . . Inverting Outputs  
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 CD74AC257,  
CD74ACT257 and CD74ACT258. The state of the Select  
input determines the particular register from which the data  
comes. The CD74AC257, CD74ACT257 and CD74ACT258  
can also be used as function generators.
