SN74LS42
One-of-Ten Decoder
The LSTTL / MSI SN74LS42 is a Multipurpose Decoder designed
to accept four BCD inputs and provide ten mutually exclusive outputs.
The LS42 is fabricated with the Schottky barrier diode process for
high speed and is completely compatible with all ON Semiconductor
TTL families.
