NXP | PCA9534D,118

The PCA9534D,118 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications

The PCA9534 consists of an 8-bit Configuration register (Input or Output selection); 8-bit Input register, 8-bit Output register and an 8-bit Polarity Inversion register (active HIGH or active LOW operation). The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register.

Features:

• 8-bit I2C-bus GPIO
• Operating power supply voltage range of 2.3 V to 5.5 V
• 5 V tolerant I/Os
• Polarity Inversion register
• Active LOW interrupt output
• Low standby current
• Noise filter on SCL/SDA inputs
• No glitch on power-up
• Internal power-on reset
• 8 I/O pins which default to 8 inputs
• 0 Hz to 400 kHz clock frequency
• Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
• Offered in four different packages: SO16, TSSOP16, and HVQFN16
