Texas Instruments (PCF8574N) I/O Expander, 8bit, 100 kHz

Product OverviewThe PCF8574N is a 8-bit input/output (I/O) Expander for the two-linebidirectional bus (I²C) is designed for 2.5 to 6V VCC operation. This deviceprovides general-purpose remote I/O expansion for most microcontroller familiesby way of the I²C interface (serial clock (SCL), serial data (SDA)). The devicefeatures an 8-bit quasi-bidirectional I/O port (P0-P7), including latchedoutputs with high-current drive capability for directly driving LEDs. Eachquasi-bidirectional I/O can be used as an input or output without the use of adata-direction control signal. At power on, the I/Os are high. In this mode,only a current source to VCC is active.Low Standby-current Consumption of 10µA MaximumI²C to Parallel-port ExpanderOpen-drain Interrupt OutputCompatible with Most MicrocontrollersLatched Outputs with High-current Drive Capability for Directly Driving LEDsLatch-up Performance Exceeds 100mA Per JESD 78, Class IIApplicationsCommunications & Networking, Computers & Computer Peripherals, ConsumerElectronics, Industrial, Automation & Process Control, Signal ProcessingProduct InformationChip Configuration: 8bitBus Frequency: 100kHzIC Interface Type: I2CSupply Voltage Min: 2.5VSupply Voltage Max: 6VInterface Case Style: DIPNo. of Pins: 16PinsNo. of I/O's: 8I/O'sProduct Range: -Automotive Qualification Standard: -MSL: -
