Key Specifications
Package: TSSOP
Mount Type: Surface Mount
Pins: 8
Operating Voltage: 3.3 V
Description
The PCA9512A/B is a hot swappable I2C-bus 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 higher.
