PCA9512A

Level shifting hot swappable I2C-bus and SMBus bus buffer

I ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per

JESD22-A115, and 1000 V CDM per JESD22-C101

I Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA

I Packages offered: SO8, TSSOP8 (MSOP8)

3. Applications

I cPCI, VME, AdvancedTCA cards and other multipoint backplane cards that are

required to be inserted or removed from an operating system
