GENERAL DESCRIPTION
The INF8574 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C). The device consists of an 8-bit quasi-bidirectional Port and an I2C interface. The INF8574 has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs. It also possesses an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I2C-bus. This means that the INF8574 can remain a simple slave device.
FEATURES
Operating supply voltage 2.5 to 6 V
Low standby current consumption of 10 A maximum
I2C to parallel port expander
Open-drain interrupt output
8-bit remote I/O Port for the I2C-bus
Compatible with most microcontrollers
Latched outputs with high current drive capability for directly driving LEDs
Address by 3 hardware address pins for use of up to 8 devices (up to 16 with INF8574A)
DIP16, space-saving SO16 or SSOP20 package.
