Descrizione
This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I²C) is designed for 2.5 V to 6 V VCC operation. The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I²C interface [serial clock (SCL), serial data (SDA)]. The device features an 8-bit quasi-bidirectional I/O port (P0–P7), 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 high. In this mode, only a current source to VCC is active.
Caratteristiche
- Low Standby - Current Consumption of 10 μA Max
- I²C to Parallel - Port Expander
- Open - Drain Interrupt Output
- Compatible With Most Microcontrollers
- Latched Outputs With High - Current Drive
- Capability for Directly Driving LEDs
- Latch - Up Performance Exceeds 100 mA Per JESD 78, Class II
Applicazioni
- Telecom Shelters: Filter Units
- Servers Routers (Telecom Switching Equipment)
- Personal Computers
- Personal Electronics
- Industrial Automation Products with GPIO - Limited Processors
