Application Circuit for the P82B715 I2C-Bus Extender for I2C-Bus Extender Paired With 2-Wire Bus Buffer Provides Bus release on VCC Failure

Application Circuit for the P82B715 I2C-Bus Extender for I2C-Bus Extender Paired With 2-Wire Bus Buffer Provides Bus release on VCC Failure. The P82B715 is based on the earliest known attempts to extend the range of an I2C-bus using emitter-followers to increase the bus sink capability, creating a low-impedance bus that can support a large capacitance
