Texas Instruments SN74AHC238/SN74AHC238-Q1 3-To-8 Line Decoder/Demux
Texas Instruments SN74AHC238/SN74AHC238-Q1 3-to-8 Line Decoder/Demux is a three-to-eight decoder with one standard output strobe (G2) and two active low output strobes (G1 and G0). When the outputs are gated by any strobe inputs, the devices are all forced into the low state. When the outputs are not disabled by the strobe inputs, only the selected output is high, while all others are low. The Texas Instruments SN74AHC238-Q1 devices are AEC-Q100 qualified for automotive applications.
Features
- Operating range 2V to 5.5V VCC
- Low delay, 10.5ns maximum (VCC = 5V, CL = 50pF)
- Latch-up performance exceeds 250mAper JESD 17
Applications
- Memory device selection with shared data bus
- Route data
- Reduce the required number of outputs for chip-select applications
