PCA9535PW

Low-voltage 16-bit I²C and SMBus low-power I/O expander with interrupt output and configuration registers

The PCA9535 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²C-bus/SMBus applications. It is designed for a wide voltage range of 2.3 V to 5.5 V with interrupt. 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 PCA9535 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. The PCA9535 has an open-drain interrupt output which is activated when any one of the GPIO changes from its corresponding input port register state. The power on reset sets the registers to default values and initializes the device state machine. The PCA9535 has three address pins A0, A1 and A2 which can be used to configure the I²C bus slave address of the device. It allows up-to eight devices to share the same I²C-bus/SMBus.

Features and benefits

  • I²C-bus to parallel port expander

  • Operating power supply voltage range of 2.3 V to 5.5 V

  • Ultra low standby current consumption:

    • 1 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)

  • 400 kHz Fast-mode I²C-bus

  • Internal power-on reset

  • No glitch on power-up

  • Latched outputs with 25 mA drive maximum capability for directly driving LEDs

  • Latch-up performance exceeds 100 mA per JESD78, Class II

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • TSSOP24 package: plastic thin shrink small outline package; 24 leads; body width 4.4 mm

  • Specified from -40 °C to +85 °C

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
