Tuotteen yleiskatsaus

The PCAL9554BBSHP is an 8-bit general purpose Input/output (GPIO) Expander with interrupt and weak pull-up 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 expander to interface with next-generation microprocessors and microcontrollers where supply levels are dropping down to conserve power. It contains the PCA9554A register set of four 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
  • Open-drain active LOW interrupt output (INT)\
  • 400kHz Fast-mode I²C-bus
  • 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
  • Input port register values changes are kept until the input port register is read
  • Floating input or pull-up/pull-down resistor enable
  • 100kR Pull-up/down resistor
