Product Overview The PCAL9535APW,118 is a 16-bit Input/output (GPIO) Expander with interrupt and reset for I²C-bus/SMBus applications. The NXP I/O expander provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. In addition to providing a flexible set of GPIOs, the wide VDD range of 1.65 to 5.5V allows the PCAL9535A to interface with next-generation microprocessors and microcontrollers where supply levels are dropping down to conserve power. It contains the PCA9535 register set of four pairs of 8-bit configuration, input, output and polarity inversion registers and additionally, the expander has Agile I/O, which are additional features specifically designed to enhance the I/O. The additional features includes programmable output drive strength, latchable inputs, programmable pull-up/pull-down resistors, maskable interrupt, interrupt status register, programmable open-drain or push-pull outputs. Low standby current consumption Schmitt-trigger action allows slow input transition and better switching noise immunity Open-drain active LOW interrupt output (INT)\ Internal power-ON reset Power-up with all channels configured as inputs No glitch on power-up Latched outputs with 25mA drive maximum capability for directly driving LEDs Latch-up performance exceeds 100 mA per JESD 78, class II Bank selectable push-pull or open-drain output stages Read-only register identifies the source of an interrupt Input port register values changes are kept until the input port register is read Floating input or pull-up/pull-down resistor enable Mask prevents the generation of the interrupt when input changes state 100kR Pull-up/down resistor Applications Communications & Networking, Sensing & Instrumentation, Power Management Product Information Chip Configuration: 16bit Bus Frequency: 400kHz IC Interface Type: I2C Supply Voltage Min: 1.65V Supply Voltage Max: 5.5V Interface Case Style: TSSOP No. of Pins: 24Pins No. of I/O's: 16I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
