Product Overview
NCA9555 is a low-voltage 16bit I²C and SMBus I/O expander with interrupt output and configuration registers. This provides 16bits of general-purpose input/output expansion for I²C-bus/SMBus applications. It is designed for a wide voltage range of 1.65V to 5.5V 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, fan control, etc. It contains a set of 8-bit input, output, configuration, and polarity inversion registers. At power-up, all IOs default to inputs. Each IO can be configured as either input or output by changing the corresponding bit in the configuration register. The data for each input or output is stored in the corresponding input or output register. The polarity inversion register can be programmed to invert the polarity of the input register.
- I²C-bus to parallel port expander, maximum low standby current consumption 2.5µA
- Noise filter on SCL and SDA inputs, Vhys = 0.10 × VCC (typical)
- 5V tolerant I/Os, 16 I/O pins which default to 16 inputs
- Open-drain active LOW interrupt output (INT), 400KHz fast-mode I²C-bus
- Internal power-on reset, no glitch on power-up
- Power-up with all channels configured as inputs with weak pull-up resistors
- Latched outputs with 25mA drive maximum capability for directly driving LEDs
- Latch-up performance exceeds 100mA per JESD78, Class II
- 24-lead plastic thin shrink small outline package (TSSOP24)
- Temperature range from -40°C to +85°C
