Logic translators, level shifters, and other similar components are immensely important in any system which has to communicate with multiple integrated circuits, especially of differing technologies. One of these components which plays an important role in bridging the gap between different technology systems is the SN74AVC16T245GQLR Translator, Buffer, Bus Switch. Tthis page will discuss the application field, technical specs, and most importantly, the working principle of the SN74AVC16T245GQLR logic translator.
Application Field
The SN74AVC16T245GQLR is mainly recommended for applications demanding a bus switch of low power, low capacitance, and high speed. This is essentially an octal bus switch in an UL & CSA listed 28 PLCC package, and is capable of handling data transfer rates of up to 100 Mbps. This device can be used for 3.3 V and 5 V digital systems, and allows power supply to run at a lower voltage. Thus, this device saves power while allowing long and efficient data transfer.Primarily intended for communication interface applications, the SN74AVC16T245GQLR allows high flexibility in data communication as it is capable of transferring data between four independent ports. There are two bi-directional ports for communication which can be used for either transmitting or receiving. The two other ports are provided for access from the integrated circuit itself. Due to its wide range of applications, the SN74AVC16T245GQLR can be used in numerous embedded applications, including automotive and medical systems, factory automation, data communications, and other industrial applications.
Technical Specifications
The SN74AVC16T245GQLR is available in a number of technical specifications. This device’s voltage capacity is between 2.7 V to 5.5 V, making it compatible with both 3.3V and 5V digital systems. Its Hot-plugging Fault is rated at a maximum of 50 mV, while its operating temperature range is 0-85 °C.The specific parameters of this device include the low power consumption of 1 mW/switch and a 400 mA peak current. The low capacitance of 8 pF is also an important feature, along with the built-in fast power-up circuit for hot swapping. The TTL and CMOS compatible outputs ensure easy operation with a range of logic families. The device also provides a low logic-level output, meaning that the logic can be detected even when the device is powered off.
Working Principle
The SN74AVC16T245GQLR works by providing a low capacitance, low power, high speed bus switch which allows data to be exchanged between different integrated circuits. To understand the working principle of the SN74AVC16T245GQLR, it is important to understand its internal architecture.
The SN74AVC16T245GQLR’s internal architecture is comprised of two octal buffers, the A side and the B side with an enable signal. Each side contains two N-channel and two P-channel FETs connected in an arrangement called a “Voltage Transfer Path”. The two FETs in the A side act as input switches for the lines for the A side, while the two FETs in the B side act as input switches for the lines for the B side. With this arrangement, data can travel between the A side and B side depending on the enable signal input.
The device has two modes of operation – input only or input and output. In input only mode, the enable signal is set to ‘0’, meaning that data can travel only from the A side to the B side and not the other way around. In input and output mode, the enable signal is set to ‘1’, allowing data to travel both ways.
The SN74AVC16T245GQLR is capable of switching the voltage levels from TTL to CMOS and vice versa and can easily handle data transfer rates of up to 100 Mbps. Additionally, its fast power-up circuit and low capacitance let it provide high-speed data transmission and ensure that the integrated circuit does not damage when powered off.
Conclusion
The SN74AVC16T245GQLR is an octal bus switch that can be used for a wide range of applications. It is designed to provide low power, low capacitance, and high speed data transfer, allowing it to bridge the gap between different technology systems and facilitate communication between integrated circuits. Its internal architecture of two octal buffers and voltage transfer paths allow it to function in either an input-only or input-and-output mode, while its compatibility with both 3.3 V and 5 V digital systems allow it to be used in a variety of industrial applications. Overall, this device is a valuable component of any system that requires the communication of multiple integrated circuits.
