74HC139
Overview
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.
- 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
