The NCA9539 provides 16 bits of General Purpose Input/Output (GPIO) expansion with interrupt and reset for I²C-bus/SMBus applications. It is designed for a wide voltage range of 1.65 V to 5.5 V. Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the interconnections to a minimum, for example, in ACPI power switch.
• I²C-bus to parallel port expander
• Operating power supply voltage range of 1.65 V to 5.5 V
• Low standby current consumption:
• 2.5 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 SDA inputs
• 5 V tolerant I/Os
• 16 I/O pins which power up configured in input state
• Open-drain active LOW interrupt output (INT)
• Reset input for resetting NCA9539 to default values (RESET)
• 400 kHz Fast-mode I²C-bus
• Internal power-on reset
• No glitch on power-up
• Latch.
