PCA9509

Level translating I2C-bus/SMBus repeater

I Operating supply voltage range of 1.0 V (0.95 V in special cases) to VCC(B) − 1.0 V on

port A, 3.0 V to 5.5 V on port B

I 5 V tolerant port B SCL, SDA and enable pins

I 0 Hz to 400 kHz clock frequency

Remark: 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, 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: TSSOP8, SO8, XQFN8
