SN54HC139

SN54HC139, SN74HC139 SCLS108E – DECEMBER 1982 – REVISED FEBRUARY 2022 SNx4HC139 Dual 2-Line To 4-Line Decoders/Demultiplexers 1 Features Targeted specifically for high-speed memory decoders and data-transmission systems Wide operating voltage range of 2 V to 6 V Outputs can drive up to 10 LSTTL loads Low power consumption, 80-μA max ICC Typical tpd = 10 ns ±4-mA output drive at 5 V Low input current of 1 μA max Incorporate two enable inputs to simplify cascading and/or data reception xA0 xA1 2 Description The SNx4HC139 contains two two-to-four decoders with one active low output strobe G. When the outputs of one channel are gated by the strobe input, they are all forced into the high state. When the outputs are not disabled by the strobe input, only the selected output is low while all others are high.
