MC74LCX258

低电压CMOS四2输入多路复用器，具有5 V容限输入和输出（三态，反相） Low-Voltage CMOS Quad 2-Input Multiplexer With 5 V−Tolerant Inputs and Outputs 3−State, Inverting

The is a high performance, quad 2-input inverting multiplexer with 3-state outputs operating from a 2.3 to 3.6V supply. Highimpedance TTL compatible inputs significantly reduce current loading toinput drivers while TTL compatible outputs offer improved switching noise performance. A V specification of 5.5V allows MC74LCX258 inputs to be safely driven from 5V devices.Four bits of data from two sources can be selected using the Select input. The four outputs present the selected data in the inverted form. The outputs may be switched to a high impedance state by placing a logic HIGH on the Output Enable OEbar input. Current drive capability is 24mA at the outputs.
