PCA9534
8-bit I2C-bus and SMBus low power I/O port with interrupt
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 four different packages: SO16, TSSOP16, and HVQFN16 (4 × 4 × 0.85 mm
and 3
× 3 × 0.85 mm versions)
