Additional Details:
The 74LVC139FPEL is available in a surface-mount package, facilitating automated assembly. Each decoder/demultiplexer has two select inputs and an enable input. When the enable input is high, all outputs are forced high, regardless of the select inputs. When the enable input is low, the outputs are decoded based on the state of the select inputs. Detailed timing diagrams and truth tables are available in the device datasheet. Proper decoupling capacitors are recommended for stable operation.
