NXP (PCA9534PW,118) I/O Expander, 8bit, 400 kHz

Product Overview The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc 8 Bit I2C Bus GPIO 5V 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 0Hz to 400kHz clock frequency Product Information Chip Configuration: 8bit Bus Frequency: 400kHz IC Interface Type: I2C, SMBus Supply Voltage Min: 2.3V Supply Voltage Max: 5.5V Interface Case Style: TSSOP No. of Pins: 16Pins No. of I/O's: 8I/O's Product Range: - Automotive Qualification Standard: - MSL: -
