What is 74LS138 decoder?
The IC 74LS138 is a 3 to 8 line decoder integrated circuit from the 74xx family of transistor-transistor-logic-gates. The main function of this IC is to decode otherwise demultiplex the applications. The setup of this IC is accessible with 3-inputs to 8-output setup.
Which of the following pin is MSB in 74LS138?
The device takes 3 input data and converts it to 8-bit data. This chip is high used in decoding in memory to minimize the effect of decoding. The chip includes three enable pin, three input pins, and 8 output pins….PIN CONFIGURATION.
| `PINS | DETAIL | |
|---|---|---|
| Y0 | Pin 15 | |
| Vcc | Pin 16 | Pin 16 will be used to power up the IC. |
What is IC 74138 for?
Use of 74138 to generate chip select logic: 74138 is used to generate chip signals.
How do I decode IC?
The three enable pins of chip (in which Two active-low and one active-high) reduce the need for external gates or inverters when expanding….74LS138 Pin configuration.
| Pin | Name | Description |
|---|---|---|
| 3 | C | Address input pin |
| 4 | G2A | Enable input (active LOW) |
| 5 | G2B | Enable input (active LOW) |
| 6 | G1 | Enable input (active HIGH) |
What is a 4 to 16 decoder?
A 4-to-16 decoder consists of 4 inputs and 16 outputs. Similar to all the decoders discussed above, in this also only one output will be low at a given time and all other outputs are high (using maxterms). The truth table of this type of decoder is shown below.
What is difference between decoder and demux?
No. A Decoder decodes an encrypted input signal to multiple output signals from one format to another format. A De-Multiplexer routes an input signal to multiple output signals.
Which IC is used for the decoder with 3 inputs and 8 outputs?
IC 74HC238
3 to 8 line decoder IC 74HC238 is used as a decoder/ demultiplexer. 3 to 8 line decoder demultiplexer is a combinational circuit that can be used as both a decoder and a demultiplexer. IC 74HC238 decodes three binary address inputs (A0, A1, A2) into eight outputs (Y0 to Y7). The device also has three Enable pins.
Which of the following is a 3/8 decoder IC?
3 to 8 line decoder IC 74HC238 is used as a decoder/ demultiplexer. 3 to 8 line decoder demultiplexer is a combinational circuit that can be used as both a decoder and a demultiplexer. IC 74HC238 decodes three binary address inputs (A0, A1, A2) into eight outputs (Y0 to Y7).
