PCA9518A

Expandable 5-channel I2C-bus hub

Features

I Expandable 5 channel, bidirectional buffer

I I2C-bus and SMBus compatible

I Active HIGH individual repeater enable inputs

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 Operating supply voltage range of 2.3 V to 3.6 V

I 5 V tolerant I2C-bus and enable pins

I 0 Hz to 400 kHz clock frequency2

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 Package offerings: SO20 and TSSOP20

Ordering information

The maximum system operating frequency may be less than 400 kHz because of the delays added by the repeater.
