Product Overview

The PCAL6416AHF,128 is a 16-bit I/O Expander provides remote I/O expansion for most microcontroller families via the I²C-bus interface. 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, it simplifies interconnection of a processor running at one voltage level to I/O devices operating at a different (usually higher) voltage level. The PCAL6416A has built-in level shifting feature that makes this device extremely flexible in mixed signal environments where communication between incompatible I/O voltages is required. Its wide VDD range of 1.65 to 5.5V on the dual power rail allows seamless communications with next-generation low voltage microprocessors and microcontrollers on the interface side (SDA/SCL) and peripherals at a higher voltage on the port side.
  • 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
  • 100kΩ Pull-up/down resistor
