74LS42 4-Line BCD To 10-Line Decimal Decoder IC

74LS42 4-Line BCD To 10-Line Decimal Decoder IC

The 74LS42 is a Multipurpose Decoder designed to accept four BCD inputs and provide ten mutually exclusive outputs. It is a member of the 74XXYY IC series. The 74LS42 is fabricated with the Schottky barrier diode process for high speed. The 74LS42 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers.
