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. PART NUMBER SN74HC139D SN74HC139DB SN74HC139N SN74HC139.
• 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
