XBLW MC14051BDR2G(XBLW)

The MC14051 is an 8-to-1 analog multiplexer/demultiplexer featuring three address select inputs (A0–A2), an active-low enable input (E), eight independent I/O channels (Y0–Y7), and a common I/O terminal (Z). The device contains eight bidirectional analog switches; one end of each switch connects to an individual I/O channel (Y0–Y7), while the other end connects to the common I/O terminal (Z). When E is low, the address inputs A0–A2 select one channel switch to enter a low-resistance ON state. When E is high, the A0–A2 inputs are ignored and all switches enter a high-impedance OFF state. The enable input (E) must be used whenever switch-state transitions are required. VDD and VSS supply the digital control inputs (A0–A2 and E), with a (VDD－VSS) operating range of 3–9V. The analog I/Os (Y0–Y7 and Z) can swing between a maximum of VDD and a minimum of VEE, with VDD－VEE not exceeding 9V. For digital multiplexer applications, VEE and VSS are tied together (typically to ground). The MC14051 is primarily used in analog multiplexing/demultiplexing, digital multiplexing, and signal gating applications.
