The SN74LVCR2245ADGVR is an advanced dual CMOS FET bus switch used as a buffer, driver, receiver and transceiver. It is designed to provide ultra-low power consumption and excellent logic performance while ensuring a high-speed signal transfer between digital logic circuits. This makes the SN74LVCR2245ADGVR an ideal choice for industrial, automotive, and military applications.

The SN74LVCR2245ADGVR is a combination of a low-voltage differential-signalling (LVDS) switch and a low-voltage (LV) pass transistor. It is designed to operate over a wide range of supply voltages, from 1V to 5.5V. The device features a low-power low-offset (LoPoLo) design, which minimizes the current draw and enables fast switching times.

The SN74LVCR2245ADGVR features two input buffers which, when enabled, convert voltage levels up to 5.5V down to a low, fixed, threshold level. This allows the device to work with either TTL logic or any logic family with a supply voltage of up to 5.5V. Its outputs are open collector outputs which can be either up to 5.5V or pulled down to logic low.

The device also has two internal voltage dividers which provide the regulated power necessary for its operation. The voltage dividers are set to 1V and 3.3V, and can be adjusted as needed. This allows the device to be used with both low-voltage and high-voltage devices. Both the negative output (OUT-) and the positive output (OUT+) have an independent logical low-level threshold voltage of -300mV.

The SN74LVCR2245ADGVR also features a power-on reset (POR) function, which is enabled by connecting the device\'s active-low input (EN) to a logic low level. When the POR is active, all inputs and outputs of the device are disabled, and its outputs remain at a logic low level until the input voltage is applied and EN is driven to a logic high. This feature prevents any unintended operation of the device when it is unpowered.

The SN74LVCR2245ADGVR also features a hot-swap control feature which prevents the voltage on the outputs from being unintentionally changed due to interference from an external source. This ensures the integrity of the data by preventing any data from being corrupted when connected devices are plugged in or removed. This feature also protects both the device and connected equipment from any potential damage due to power surges.

Finally, the SN74LVCR2245ADGVR also features an on-chip ESD protection with up to 2000V of protection, making it ideal for use in industrial environments where high voltages are expected. This feature helps to prevent any permanent damage to the device from high-voltage transients.

The SN74LVCR2245ADGVR is a powerful, low-power logic device that can be used in a wide variety of applications. Its multiple buffering, driver, receiver, and transceiver capabilities, combined with its low-voltage and low-power capabilities, make it an ideal solution for automotive, industrial, and military applications.
