NCA9595-Q100 - Low-voltage 16-bit I2C and SMBus I/O expander

General Description

The NCA9595-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²Cbus/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.

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 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 SD.

NCA9595-Q100 Low-voltage 16-bit I²C and SMBus I/O expander with interrupt output, configuration registers and programmable pull-up resistors Rev. 1 — 25 April 2023 Product data sheet 1. General description The NCA9595-Q100 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²Cbus/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. The NCA9595-Q100 contains a set of 8 bit input, output, configuration, polarity inversion and configuration pull-up registers.
