GN4051B

GN4051B 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 terminal of each switch connects to an individual I/O channel (Y0–Y7), while the other terminal connects to the common I/O (Z). When E is low, the channel selected by A0–A2 is turned on in a low-impedance conductive state. When E is high, the A0–A2 settings are ignored and all switches are in a high-impedance off state. The enable input (E) must be used whenever switch state transitions are required. VDD and VSS are the supply voltages for the digital control inputs (A0–A2 and E). The (VDD − VSS) range is 3–9V. The analog I/O pins (Y0–Y7 and Z) can swing from a minimum of VEE to a maximum of VDD. Neither VDD nor VEE shall exceed 9V. For use as a digital multiplexer, VEE and VSS are connected together (typically tied to ground).
