PCA9538

8-bit I2C-bus and SMBus low power I/O port with interrupt and reset

I 8 I/O pins which default to 8 inputs

I 0 Hz to 400 kHz clock frequency

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 Offered in three different packages: SO16, TSSOP16 and HVQFN16
