54LS42A 1-of-10 Decoder

PublishTime：2022-03-26

■The LSTTL/MSI 54LS42A is a multipurpose decoder designed to accept four BCD inputs and provide ten mutually exclusive outputs. The LS42A is fabricated with the Schottky barrier diode process for high-speed and is completely compatible with all Motorola TTL families.
◆Multifunction Capability
◆Demultiplexing Capability
◆Mutually Exclusive Outputs
◆Input Clamp Diodes Limit High-Speed Termination Effect.
●FUNCTIONAL DESCRIPTION:
■The LS42A decoder accepts four active HIGH BCD inputs and provides ten mutually exclusive active LOW outputs, as shown by the logic symbol or diagram. The active LOW outputs facilitate addressing over MSI units with LOW input enables.
■The logic design of the LS42A ensures that all outputs are HIGH when binary codes greater than nine are applied to the inputs.
■The most significant input D produces a useful inhibit function when the LS42A is used as a one-of-eight decoder. The D input can also be used as the Data input in an 8-output demultiplexer application.
