ONE-OF-TEN DECODER
The LSTTL / MSI SN54 / 74LS42 is a Multipurpose Decoder designed to ac-
cept 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 Motorola TTL families.
• Multifunction Capability
• Mutually Exclusive Outputs
• Demultiplexing Capability
• Input Clamp Diodes Limit High Speed Termination Effects
