Additional Details:

The MC54HC4051J is controlled by three binary address inputs (A, B, C) and an enable input (INH). The address inputs select one of the eight channels for connection to the common output. The INH input disables all channels when high. The package type is a through-hole package. Consult the datasheet for specific electrical characteristics, timing diagrams, and recommended operating conditions. It is also available in surface mount packages.
