Quad 2-Input Multiplexer
with Three-State Outputs
August 1998 - Revised May 2000
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 highimpedance state regardless of all other input conditions.
• CD74ACT258 . . . . . . . . . . . . . . . . . . . Inverting Outputs
• Buffered Inputs
• Typical Propagation Delay
- 4.4ns at VCC = 5V, TA = 25oC, CL = 50pF
• Exceeds 2kV ESD Protection MIL-STD-883, Method
3015
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.
