Translators, level shifters, and interfaces have become increasingly critical components as integrated circuits have become denser and more complex. The SN74AVC8T245DGVR is a dedicated logic device designed to meet stringent requirements in space-limited designs. Designers turn to this robust solution to handle bidirectional voltage-level transitions between two independent power domains.

The SN74AVC8T245DGVR is a bidirectional level-shifter designed to address multiple voltage-level conversion applications. Targeting applications such as I2C, SPI, or JTAG bus interfaces, this logic solution provides eight individually controlled full-duplex channels, with addressable input and output drivers. The channels support input voltage levels ranging from +0.55V to +5.5V, and output voltage levels ranging from +4.4V to +12V.

The device is tolerant of large voltage differences between the input and output domains, since it uses a charge-pump topology to generate the supply on the output side of the logic device. This also increases the power efficiency since the output side does not have a dedicated supply. The logic gate section of the device uses a low-power, CMOS process, with power consumption as low as 2mW consumption.

The SN74AVC8T245DGVR provides high throughput and operates at 1.2GHz switching speed with a fast response time of 350ps. This allows the device to handle high-speed data transmissions, while simultaneously reducing design complexity. The device also has a low propagation delay, ensuring reliable performance in applications requiring high-speed data transfer.

The device is available in a variety of package types, from lead-free ultra thin packaging to low-profile TSSOP. VDD and VSS pins are provided for each supply, allowing for efficient power delivery. The device has four shiftable address pins and one fixed address, allowing for customizing each output. The SN74AVC8T245DGVR is available in either 8-channel or 16-channel options.

The SN74AVC8T245DGVR is designed primarily for embedded applications where signals must be transferred between two different voltage domains. The device can be used in applications such as MCU and FPGA communication links, circuit board architecture, and in many other applications such as data bus buffers, bus-bridge drivers, USB interfaces, and other serial communication links. The device also has an integrated connection detect feature, making it suitable for many other connecting applications.

In summary, the SN74AVC8T245DGVR is a dedicated logic device offering full-duplex bidirectional level-shifting capabilities in a space-efficient package. Key features and benefits of this solution include low power consumption, fast switching, propagation delay, and robust design for applications ranging from data-bus buffers, interconnect links, to digital signal multiplexers.
