Nxp (2820290) I/O Expander, 8bit, 400 kHz, I2C, SMBus, 2.3 V, 5.5 V, TSSOP

Product OverviewThe PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purposeparallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and wasdeveloped to enhance the NXP Semiconductors family of I2C-bus I/O expanders. Theimprovements include higher drive capability, 5 V I/O tolerance, lower supplycurrent, individual I/O configuration, 400 kHz clock frequency, and smallerpackaging. I/O expanders provide a simple solution when additional I/O is neededfor ACPI power switches, sensors, push buttons, LEDs, fans, etc8 Bit I2C Bus GPIO5V tolerant I/OsPolarity Inversion registerActive LOW interrupt outputLow standby currentNoise filter on SCL/SDA inputsNo glitch on power upInternal power on reset8 I/O pins which default to 8 inputs0Hz to 400kHz clock frequencyProduct Information:Chip Configuration: 8bitBus Frequency: 400kHzIC Interface Type: I2C, SMBusSupply Voltage Min: 2.3VSupply Voltage Max: 5.5VInterface Case Style: TSSOPNo. of Pins: 16PinsNo. of I/O's: 8I/O'sProduct Range: -MSL: -
