Product Overview

The PCF8575CPW is a 16-bit I/O Expander for the two-line bidirectional bus (I²C) is designed for 4.5 to 5.5V VCC operation. The PCF8575C provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface serial clock (SCL) and serial data (SDA). The device features a 16-bit quasi-bidirectional input/output (I/O) port (P07-P00, P17-P10), including latched outputs with high-current drive capability for directly driving LEDs. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. At power on, the I/Os are in 3-state mode. The strong pull-up to VCC allows fast-rising edges into heavily loaded outputs. This device turns on when an output is written high and is switched off by the negative edge of SCL. The I/Os should be high before being used as inputs. After power on, as all the I/Os are set to 3-state, all of them can be used as inputs.
  • Open-drain interrupt output
  • Compatible with most microcontrollers
  • 400kHz Fast I²C bus
  • Address by 3 hardware address pins for use of up to 8 devices
  • Latched outputs with high-current drive capability for directly driving LEDs
  • Latch-up performance exceeds 100mA per JESD 78, class II
  • 10µA Maximum low standby-current consumption
  • Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
