Product Overview

The PCA9535PWR is a remote 16-bit I²C and SMBus low-power I/O Expander with interrupt output and configuration registers. It provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface (serial clock (SCL), serial data (SDA)). The PCA9535 consists of two 8-bit configuration (input or output selection), input port, output port and polarity inversion (active-high or active-low operation) registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding input or output port register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master.
  • 1μA Maximum low standby-current consumption
  • I²C to parallel port expander
  • Open-drain active-low interrupt output
  • Compatible with most microcontrollers
  • Address by three hardware address pins for use of up to eight devices
  • Polarity inversion register
  • Latched outputs with high-current drive capability for directly driving LEDs
  • Latch-up performance exceeds 100mA per JESD 78
  • ESD protection exceeds JESD 22
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
