It provides general-purpose remote I\/O expansion for most microcontroller families via the I²C interface [serial clock (SCL), serial data (SDA)]. The PCA9534A consists of one 8-bit configuration (input or output selection), input port, output port and polarity inversion (active high or active low) register. At power on, the I\/Os are configured as inputs. However, 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. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master. The system master can reset the PCA9534A in the event of a timeout or other improper operation by utilizing the power-on reset feature. \u003cul\u003e \u003cli\u003eOpen-drain active-low interrupt (INT)\\ output\u003c\/li\u003e \u003cli\u003eThree hardware address pins allow up to eight devices on the I²C\/SMBus\u003c\/li\u003e \u003cli\u003eAllows up to 16 devices on the I²C\/SMBus when used in conjunction with the PCA9534A\u003c\/li\u003e \u003cli\u003eInput\/output configuration register\u003c\/li\u003e \u003cli\u003ePolarity inversion register\u003c\/li\u003e \u003cli\u003eInternal power-ON reset\u003c\/li\u003e \u003cli\u003ePower-up with all channels configured as inputs\u003c\/li\u003e \u003cli\u003eNo glitch on power-up\u003c\/li\u003e \u003cli\u003eNoise filter on SCL\/SDA input\u003c\/li\u003e \u003cli\u003eLatched outputs with high-current drive maximum capability for directly driving LEDs\u003c\/li\u003e \u003cli\u003eLatch-up performance exceeds 100mA per JESD 78, class II\u003c\/li\u003e \u003cli\u003e1µA Maximum low standby current consumption\u003c\/li\u003e \u003cli\u003e400kHz Fast I²C bus\u003c\/li\u003e \u003cli\u003eGreen product and no Sb\/Br\u003c\/li\u003e \u003c\/ul\u003e Applications \u003cp\u003e Communications \u0026amp; Networking, Industrial \u003c\/p\u003e Warnings Device has limited built-in ESD protection.
