74LV4051DB

8通道模拟多路复用器/ 8-channel analog multiplexer/demultiplexer

General description

The 74LV4051 is an 8-channel analog multiplexer/demultiplexer with three digital select inputs S0 to S2, an active-LOW enable input E, eight independent inputs/outputs Y0 to Y7 and a common input/output Z. It is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC4051 and 74HCT4051. WithE LOW, one of the eight switches is selected low impedance ON-state by S0 to S2. WithE HIGH, all switches are

in the high-impedance OFF-state, independent of S0 to S2.
