Product Introduction
This 16-bit I/O expander for two-wire bidirectional bus (I²C) is designed for 2.5V to 5.5V VCC operating voltage.
The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface [Serial Clock (SCL), Serial Data (SDA)].
This 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 either an input or output without the need for a data direction control signal. At power-on, these I/Os are at a high level. In this mode, only one current source connected to VCC is active.
Features
- I²C to parallel port expander
- Open-drain interrupt output
- 10μA low standby current consumption (maximum)
- Compatible with most microcontrollers
- 400kHz fast I²C bus
- 3 hardware address pins for addressing up to 8 devices
- Latched outputs with high-current drive capability for direct LED driving
- Current source connected to VCC for actively driving outputs high
- Latch-up performance exceeds JESD 78 Class II specification by 100mA
- ESD protection performance exceeds JESD 22 specification requirements: 2000V Human Body Model, 200V Machine Model, 1000V Charged Device Model
Applications
- Telecom shelter: filter units
- Servers
- Routers (telecom switching equipment)
