The PCF8574PWR is a high-quality, low-power CMOS technology product from Texas Instruments, a leading company in the semiconductor industry.

• Type: 8-bit I/O expander for the two-line bidirectional bus (I2C)
• Feature: 8-bit quasi-bidirectional I/O port (P0-P7), including latched outputs with high current drive capability for directly driving LEDs.
• Feature: Has an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller.
• Compatibility: Compatible with most microcontrollers and allows for a significant expansion of I/O capability.
• Address Pins: Has three hardware address pins that allow eight devices to operate on the same bus.
• Voltage Range: Operates at a supply voltage range of 2.5 to 6V.
• Temperature Range: Designed to operate at temperatures ranging from -40°C to 85°C.
• Package: Packaged in a compact TSSOP casing.
