PCA9517

Level translating I2C-bus repeater

I Active HIGH repeater enable input

I Open-drain input/outputs

I Lock-up free operation

I Supports arbitration and clock stretching across the repeater

I Accommodates Standard mode and Fast mode I2C-bus devices and multiple masters

I Powered-off high-impedance I2C-bus pins

I A-side operating supply voltage range of 0.9 V to 5.5 V

I B-side operating supply voltage range of 2.7 V to 5.5 V

I 5 V tolerant I2C-bus and enable pins

I 0 Hz to 400 kHz clock frequency (the maximum system operating frequency may be

less than 400 kHz because of the delays added by the repeater).

I ESD protection exceeds 2000 V HBM per JESD22-A114, 150 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 and TSSOP8
