General Description

The NCA9555-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²C-bus/SMBus applications.

It is designed for a wide voltage range of 1.65 V to 5.5 V with interrupt and default pull-up resistors on GPIOs.

Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs and fan control.

Key Features

  • Automotive product qualification in accordance with AEC-Q100 (Grade 1).
  • Specified from -40 °C to +125 °C.
  • I²C-bus to parallel port expander.
  • Operating power supply voltage range of 1.65 V to 5.5 V.
  • Low standby current consumption:.
  • 4.0 µA (maximum).
  • Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs.
  • Vhys = 0.10 × VCC (typical).
  • Noise filter on SCL and.
