P82B715

I2C-bus extender

I Supply voltage range 3 V to 12 V

I Clock speeds to at least 100 kHz and 400 kHz when other system delays permit

I ESD protection exceeds 2500 V HBM per Mil. Std 883C-3015.7 and 400 V MM per

JESD22-A115 (I/Os have diodes to VCC and GND)

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

3.

Applications

I Increase the total connected capacitance of an I2C-bus system to around 3000 pF

I Drive I2C-bus signals over long cables to approximately 50 meters or 3000 pF

I Drives ×10 lower impedance bus wiring for improved noise immunity

I Multi-drop distribution of I2C-bus signals using low cost twisted-pair cables

I AdvancedTCA radial IPMB architecture

I Driving 30 mA Fm+ devices from standard 3 mA parts
