The SN74HC367PWR is a high-speed, low-power 3 to 8-line decoder/demux manufactured by Texas Instruments. Primarily used for multiplexing applications, this logic device can provide solutions for a wide range of logic applications, from driving multiplex LED displays to interfacing on bit-wide buses. This paper will discuss the application field and working principles of the SN74HC367PWR.

Applications

The SN74HC367PWR can be used in a variety of applications, including data transmission and multiplexing. Its two main inputs, A and B, can be used to select one of the 8 active inputs, allowing the selected line to be passed on and amplified. This can be used in a variety of applications like LED displays, where data on 8 separate lines needs to be multiplexed. It can also be used in data transmission applications, where data needs to be passed on one line at a time.

The SN74HC367PWR can also be used as an address decoder in programs like programmable logic arrays. With its two main inputs, A and B, it can be used to select one of 8 different outputs, allowing the programmable logic array to select a particular address from the 8 available ones.

Working Principle

The SN74HC367PWR is a 3 to 8-line decoder/demux that uses two main inputs, A and B, to select one of the 8 available lines. When the two main inputs, A and B, are binary encoded, they generate a unique 3-bit code that select which of the 8 lines is active. This code is used to control which line will be amplified and passed through the device.

The SN74HC367PWR also contains internal logic organized in 8 blocks of S-R (Set-Reset) latches. These latches can be used to either amplify the selected input or to set all the outputs to 0 (reset, ground). Each latch is capable of driving up to 8 outputs, allowing for the buffering of 8 devices. The outputs are also TTL-compatible, which allows for easy interfacing with other logic devices.

Conclusion

The SN74HC367PWR is a versatile 3-to-8 line decoder/multiplexer manufactured by Texas Instruments. It can be used in a variety of applications, from LED displays to data transmission applications. It is also capable of address decoding, allowing for easier programmable logic array interfacing. The device is powered by two main inputs, A and B, which generate a unique 3-bit code which selects one of the 8 lines. Additionally, the device is capable of driving 8 separate outputs, allowing for the buffering of 8 devices.
