INTEGRATED CIRCUITS PCA9512 Level shifting hot swappable I2C and SMBus buffer Product data sheet 2004 Oct 05 Philips Semiconductors Philips Semiconductors Product data sheet Level shifting hot swappable I2C and SMBus buffer DESCRIPTION The PCA9512 is a hot swappable I2C and SMBus buffer that allows I/O card insertion into a live backplane without corruption of the data and clock buses and includes two dedicated supply voltage pins to provide level shifting between 3.3 V and 5 V systems while maintaining the best noise margin for each voltage level. Either pin may be powered with supply voltages ranging from 2.7 V to 5.5 V with no constraints on which supply voltage is...
