This device is ideally suited for high speed bipolar memory chip select address decoding.. I need to implement the function below using 3x8 decoder (74LS138) and a minimum number of gates but I did not see 74LS138 before. F = (A.B)' I implement the function using a normal 3x8 decoder b.
A decoder is a multiple-input, multiple-output logic circuit that converts coded inputs into coded outputs, where the input and output codes are different. Binary Decoder has n inputs and 2n outputs also called as n-to-2n decoder.. Motorola SN54/74LS138 known to be 1-of-8 decoder or demultiplexer which is designed for high speed bar memory chip select address decoding. Below diagram illustrates logic diagram of this SN54/74LS138 demultiplexer.. 5-1 FAST AND LS TTL DATA DUAL 1-OF-4 DECODER/ DEMULTIPLEXER The LSTTL/MSI SN54/74LS139 is a high speed Dual 1-of-4 Decoder/De-multiplexer. The device has two independent decoders, each accepting two.
