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

• CD74ACT258 . . . . . . . . . . . . . . . . . . . Inverting Outputs

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.

• Buffered Inputs

• Typical Propagation Delay

- 4.4ns at V

= 5V, T = 25 C, C = 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.
