$1.14The Story
NCA9539PW-Q100J is a low-voltage 16bit IĀ²C and SMBus low-power I/O expander with interrupt output, reset pin and configuration registers. It is designed for a wide voltage range of 1.65V to 5.5V. This GPIO expander provides 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. It contains a set of 8bit 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 read register. It has an open-drain interrupt output which is activated when any one of the GPIO changes from its corresponding input port register state.
- Automotive product qualification in accordance with AEC-Q100 (Grade 1)
- IĀ²C-bus to parallel port expander, supply current is 4ĀµA maximum at (VCC = 3.6V to 5.5V)
- 5V tolerant I/Os, 16 I/O pins which power up configured in input state
- Open-drain active LOW interrupt output (INT)
- 400KHz Fast-mode IĀ²C-bus, internal power-on reset, no glitch on power-up
- Latched outputs with 25mA drive maximum capability for directly driving LEDs
- Latch-up performance exceeds 100mA per JESD78, class II, CMOS logic switching levels
- Input capacitance is 1.5pF typical at (VI = VCC or GND; VCC = 1.65V to 5.5V)
- Operating temperature range from -40Ā°C to +125Ā°C
- Package style is TSSOP24
