The SN74AVC1T45DBVRE4 belongs to a family of devices called logic translators, level shifters, which are integrated circuits designed to convert between logic levels of different families of logic. This particular device is an octal non-inverting buffer/driver with 3-state outputs designed to translate between various families of logic.

The device is designed to provide a 2 V to 6 V output (on the "B" side of the device) in response to a compatible input on the "A" side. It is designed to allow the output state of B side to mimic the A side regardless of the logic level of the output. The SN74AVC1T45DBVRE4 has an enable control, allowing it to be placed into either an active or a 3-state mode.

It is most often used in a variety of applications because of its ability to provide both a buffered and driven output. The buffered outputs provide a voltage swing from 0 V to Vcc, so it can be used to drive large capacitive loads and long cables. The driven outputs offer an improved propagation delay and have an inherent Schmitt-trigger action on the input.

Application Field

The SN74AVC1T45DBVRE4 is often used in a variety of applications, including:

• Line receivers
• Networking applications
• Data communication
• Exchangeable mux systems
• Broadband communication systems
• Current and temperature sensing systems

Working Principle

The SN74AVC1T45DBVRE4 operates on a simple principle, translating between different logic levels. It accepts high-voltage input from the "A" side, which is then buffered and driven to the "B" side. The device has an enable control, allowing it to be placed into either an active or a 3-state mode. When in the active mode, the SN74AVC1T45DBVRE4 acts as a translator, amplifying and translating the input signal from one logic family to the other. When placed in the 3-state mode, the output of the device is disabled and the output nodes are held in a high impedance state.

The device is designed to provide improved performance, offering fast propagation delay, which is the amount of time that passes between when an input is applied and when an output is produced, as well having an inherent Schmitt-trigger action on the input. This performance is augmented by the buffered outputs, allowing the SN74AVC1T45DBVRE4 to drive large capacitive loads and long cables.

In summary, the SN74AVC1T45DBVRE4 is an octal non-inverting buffer/driver with 3-state outputs designed to translate between various families of logic. It is used in various applications because of its ability to provide both a buffered and driven output. It is designed to provide a 2 V to 6 V output in response to a compatible input and has an enable control allowing it to be placed into either an active or a 3-state mode.
