CD74ACT258MG4

四2输入多路复用器具有三态输出 Quad 2-Input Multiplexer with Three-State Outputs

Description

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. WhenOE is HIGH, all of the outputs Y orY are in the high impedance state regardless of all other input conditions.
