HANSCHIP semiconductor 74HC4052PWRG

The 74HC4052 is a 2-channel, 4-to-1 analog multiplexer/demultiplexer with a common enable input. Each multiplexer has four independent inputs/outputs (Y0 to Y3), a common input/output (Z), and selection inputs (A). The common enable control includes two selection inputs A0 and A1, and an active-low enable input E. Each channel contains four bidirectional analog switches, with one side of each switch connected to the individual inputs/outputs (Y0 to Y3) and the other side connected to the common input/output (Z). When E is LOW, one of the four switches is selected (low-resistance ON state) by A0 and A1. When E is HIGH, all switches are in the high-impedance OFF state, regardless of the states of A0 and A1. VDD and VSS are the supply voltages for the digital control inputs (A0, A1, and E). The (VDD - VSS) range is 3~9V. The analog inputs/outputs (Y0~Y3 and Z) can swing between a maximum of VDD and a minimum of VEE. (VDD - VEE) must not exceed 9V. When used as a digital multiplexer, VEE and VSS are connected together (typically to GND).
