CD74ACT258中文资料具有三态输出的四路 2 输入反相多路复用器数据手册TI规格书

描述 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. 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.
