NXP (PCAL6416AHF,128) I/O Expander, 16bit, 400 kHz

Product OverviewThe PCAL6416AHF,128 is a 16-bit I/O Expander provides remote I/O expansion formost microcontroller families via the I²C-bus interface. The NXP I/O expanderprovides a simple solution when additional I/Os are needed while keepinginterconnections to a minimum. In addition to providing a flexible set of GPIOs,it simplifies interconnection of a processor running at one voltage level to I/Odevices operating at a different (usually higher) voltage level. The PCAL6416Ahas built-in level shifting feature that makes this device extremely flexible inmixed signal environments where communication between incompatible I/O voltagesis required. Its wide VDD range of 1.65 to 5.5V on the dual power rail allowsseamless communications with next-generation low voltage microprocessors andmicrocontrollers on the interface side (SDA/SCL) and peripherals at a highervoltage on the port side.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: HWQFNNo. of Pins: 24PinsNo. of I/O's: 16I/O'sProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
