Texas Instruments SN74HCS139/SN74HCS139-Q1 Decoder/Demultiplexer
Texas Instruments SN74HCS139/SN74HCS139-Q1 Decoder/Demultiplexer is two two-to-four decoders with one active low output strobe (G). When the outputs of one channel are gated by the strobe input, the outputs 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. The Texas Instruments SN74HCS139-Q1 devices are AEC-Q100 qualified for automotive applications.
Features
- 2V to 6V wide operating voltage range

- –40°C to +125°C, TA extended ambient temperature range
- Low power consumption
- Typical ICC of 100nA
- Typical input leakage current of ±100nA
Applications
- Memory device selection with a shared data bus
- Route data
- Reduce the required number of outputs for chip-select applications
