The ’HC139 and ’HCT139 devices contain two independent binary to one of four decoders each with a single active low enable input (1E or 2E). Data on the select inputs (1A0 and 1A1 or 2A0 and 2A1) cause one of the four normally high outputs to go low. If the enable input is high all four outputs remain high. For demultiplexer operation the enable input is the.
• Multifunction Capability - Binary to 1 of 4 Decoders or 1 to 4 Line Demultiplexer
• Active Low Mutually Exclusive Outputs
• Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL Logic ICs
• HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC at VCC = 5V
