all the segment outputs are HIGH independent of all other input conditions
and Year with Leap-Year Compensation Valid Up to 2100

Use the Ethernet Library to write sketches which connect to the internet using the shield
so that only one wire (and ground) needs to be connected from a central microprocessor
74HC157 (Quad 2-input Multiplexer) load cell 1 kg all the segment outputs areIntroduction : 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
