Description
The IC 74HC42 is a 1-of-10 BCD to Decimal Decoder. It accepts four BCD inputs (0A to 3A) and outputs ten mutually exclusive outputs (0Y to 9Y). When a binary code greater than nine is applied to the inputs, the logic design ensures that all outputs are HIGH. When used as a 1-of-8 decoder, the most significant input (3A) generates a useful inhibit function. The 3A input can also be used as the data input in an 8-output demultiplexer application. Clamp diodes are among the inputs. This enables the use of current-limiting resistors to interface inputs to voltages greater than VCC.
