74HC157 (Quad 2-input Multiplexer) Door Switch and a magnetometer into aIntroduction : 74HC157 (Quad 2 input Multiplexer). 74HC1457 is a quad 2 input multiplexer. The device features select (S) and enable E inputs. A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E forces all the outputs (1Y to 4Y) LOW. Inputs include clamp diodes . This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Features ; Supply voltage : 2 6 v. Low input current : 1 mA. Temperture
