The DS75176BTN/NOPB is a 8-bit bi-directional I²C-bus and SMBus voltage level-shifter with output enable pin. This device enables communication between any I²C-bus and SMBus devices, regardless of their respective voltage levels. This level shifter is used to interface any two interface systems with two different power levels. The device allows two different logic levels to be translated from one device to another over a specified voltage range. The DS75176BTN/NOPB allows a I²C-bus or SMBus slave device to be connected to a higher-voltage I²C-bus or SMBus master.

This device is suitable for battery-powered applications or for any level-shifting application that contains different voltage levels. It is designed to provide a level-shifting interface between I²C-bus and SMBus devices at different voltage levels up to 10V. The device supports I²C fast-mode (400kHz) and fast-mode plus (1MHz) protocol with various timing options, and supports an output enable line to enable/disable the output signals.

The DS75176BTN/NOPB has a 8-bit, latched bus interface with bidirectional current source, which provides pulled-up or pulled-down control between the I²C-bus and SMBus nodes. The output enable-pin has an internal pull-down resistor, which can be used to configure the output voltage level when the device is disabled. It features thermal shutdown protection to protect the device from destruction due to overheating.

The working principle of the DS75176BTN/NOPB is based on the capacitive isolation and bi-directional current-source stages. The capacitive-isolation stage provides level-shifting for the I²C-bus and SMBus signals between 0.8V and 10V. The bi-directional current-source stages buffer the signal from the bus and provide proper voltage levels to the output. An output enable pin controls the output driving capability of the device.

The DS75176BTN/NOPB is mainly used in the following applications:

• Consumer electronic applications such as TV and audio systems
• Industrial control systems
• Medical equipment
• Portable battery-powered devices
• Retrofit systems
• Security systems
• Automotive electronics
• GPS and navigation systems

In conclusion, the DS75176BTN/NOPB is a level-shifting, 8-bit bidirectional I²C-bus and SMBus voltage level-shifter with output enable pin that enables communication between any I²C-bus or SMBus device, regardless of their respective voltage levels. It is mainly used in consumer,
