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

Product Overview The PCF8574N is a 8-bit input/output (I/O) Expander for the two-line bidirectional bus (I²C) is designed for 2.5 to 6V VCC operation. This 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. Low Standby-current Consumption of 10µA Maximum 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 100mA Per JESD 78, Class II Applications Communications & Networking, Computers & Computer Peripherals, Consumer Electronics, Industrial, Automation & Process Control, Signal Processing Product Information Chip Configuration: 8bit Bus Frequency: 100kHz IC Interface Type: I2C Supply Voltage Min: 2.5V Supply Voltage Max: 6V Interface Case Style: DIP No. of Pins: 16Pins No. of I/O's: 8I/O's Product Range: - Automotive Qualification Standard: - MSL: -
