PCA9517A

Level translating I2C-bus repeater

2. Features

I 2 channel, bidirectional buffer isolates capacitance and allows 400 pF on either side of

the device

I Voltage level translation from 0.9 V to 5.5 V and from 2.7 V to 5.5 V

I Footprint and functional replacement for PCA9515/15A

I I2C-bus and SMBus compatible

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 Port A operating supply voltage range of 0.9 V to 5.5 V

I Port B 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 5500 V HBM per JESD22-A114, 450 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
