TECHNICAL DATA
GENERAL DESCRIPTION
The
KK
F8574 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most
microcontroller families via the two-line bidirectional bus (I
2
C).
The device consists of an 8-bit quasi-bidirectional Port and an I
2
C interface. The
KK
F8574 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 I
2
C-bus. This means that the
KK
F8574 can remain a
simple slave device.
FEATURES
Operating supply voltage 2.5 to 6 V
Low standby current consumption of 10
A maximum
I
2
C to parallel port expander
Open-drain interrupt output
8-bit remote I/O Port for the I
2
C-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
KK
F8574A)
DIP16, space-saving SO16 or SSOP20 package.
