Product OverviewThe PCAL9539APW,118 is a 16-bit Input/output (GPIO) Expander with interrupt andreset for I²C-bus/SMBus applications. The NXP I/O expander provides a simplesolution when additional I/Os are needed while keeping interconnections to aminimum. In addition to providing a flexible set of GPIOs, the wide VDD range of1.65 to 5.5V allows the PCAL9539A to interface with next-generationmicroprocessors and microcontrollers where supply levels are dropping down toconserve power. The expander contains the PCA9539 register set of four pairs of8-bit configuration, input, output and polarity inversion registers andadditionally, the PCAL9539A has Agile I/O, which are additional featuresspecifically designed to enhance the I/O. The additional features includesprogrammable output drive strength, latchable inputs, programmablepull-up/pull-down resistors, maskable interrupt, interrupt status register,programmable open-drain or push-pull outputs.Low standby current consumptionSchmitt-trigger action allows slow input transition and better switching noiseimmunityOpen-drain active LOW interrupt output (INT)\Internal power-ON resetPower-up with all channels configured as inputsNo glitch on power-upLatched outputs with 25mA drive maximum capability for directly driving LEDsLatch-up performance exceeds 100 mA per JESD 78, class IIBank selectable push-pull or open-drain output stagesRead-only register identifies the source of an interruptInput port register values changes are kept until the input port register isreadFloating input or pull-up/pull-down resistor enableMask prevents the generation of the interrupt when input changes state100kR Pull-up/down resistorApplicationsCommunications & Networking, Sensing & Instrumentation, Power ManagementProduct InformationChip Configuration: 16bitBus Frequency: 400kHzIC Interface Type: I2CSupply Voltage Min: 1.65VSupply Voltage Max: 5.5VInterface Case Style: TSSOPNo. of Pins: 24PinsNo. of I/O's: 16I/O'sProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
