Texas Instruments PCF8574N I/O Expander 8bit 100 kHz I2C 2.5 V 6 DIP

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

Warnings Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
