2x PCF8574P I/O Extension Board 8574 NXP

- The PCF8574P is an 8-bit remote I / O expander for the I2C bus with 16-pin DIP packet interrupt. - Provides general-purpose remote I / O expansion via a two-wire, two-way I2C bus (Serial Clock (SCL), Serial Data (SDA)).
- Devices consist of eight quasi-directional ports , 100KHz I2C bus interface, three hardware address inputs and interrupt output operating between 2.5V and 6V.
- Quasi-bidirectional port can be independently assigned as one input to monitor interrupt status or keyboards or as an output to activate indicating devices like LEDs. - System Master can read from the input port or write to the output port through a single register.

2x PCF8574P I/O Extension Board 8574 NXP description

- The PCF8574P is an 8-bit remote I / O expander for the I2C bus with 16-pin DIP packet interrupt.
- Provides general-purpose remote I / O expansion via a two-wire, two-way I2C bus (Serial Clock (SCL), Serial Data (SDA)).
- Devices consist of eight quasi-directional ports , 100KHz I2C bus interface, three hardware address inputs and interrupt output operating between 2.5V and 6V.
- Quasi-bidirectional port can be independently assigned as one input to monitor interrupt status or keyboards or as an output to activate indicating devices like LEDs.

- System Master can read from the input port or write to the output port through a single register.
- The Low current consumption of 2.5μA (typical, static) is ideal for mobile applications and blocked output ports for to drive LEDs directly.
- Internal Power Reset (POR) initializes I / O as inputs with a weak internal pull up current source of up to 100μA.

2x PCF8574P I/O Extension Board 8574 NXP features:

- I2C bus to parallel port expander
- Remote 8-bit I / O pins which by default are inputs at power on
- Full capacity packet sink sink
- Active low open drain interrupt output
- Eight programmable slave addresses using three address pins
- Low standby current is typically 2.5μA < br /> - Operating temperature range -40 ° C to 85 ° C
- Offers ESD protection
- Quantity: 2 units
