Product Summary

The PCA9535 is a 24-pin CMOS device that provide 16 bits of
General Purpose parallel Input/Output (GPIO) expansion for I
2
C/SMBus applications and was developed to enhance the Philips
family of I
2
C I/O expanders. The improvements include higher drive
capability, 5 V I/O tolerance, lower supply current, individual I/O
configuration, and smaller packaging. I/O expanders provide a
simple solution when additional I/O is needed for ACPI power
switches, sensors, pushbuttons, LEDs, fans, etc.

Features

? Operating power supply voltage range of 2.3 V-5.5 V
? 5 V tolerant I/Os
? Polarity inversion register
? Active LOW interrupt output
? Low stand-by current
? Noise filter on SCL/SDA inputs
? No glitch on power-up
? Internal power-on reset
? 16 I/O pins which default to 16 inputs
? 0 to 400 kHz clock frequency
? ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V
MM per JESD22-A115, and 1000 V CDM per JESD22-C101
? Latch-up testing is done to JESDEC Standard JESD78 which
exceeds 100 mA
? Offered in three different packages: SO24, TSSOP24, and
HVQFN24
