INF8574 - Remote 8-Bit. I/O Expander for I2C Bus

Description

e h The INF8574 is a silicon CMOS circuit.

It provides general purpose remote I/O expansion for most S microcontroller families via the two-line bidirectional bus (I C).

a t The device consists of an 8-bit quasi-bidirectional Port and an I C interface.

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.

w simple slave device. INF8574 e GENERAL DESCRIPTION e h The INF8574 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most S microcontroller families via the two-line bidirectional bus (I C). a t The device consists of an 8-bit quasi-bidirectional Port and an I C interface. The INF8574 has a low current a consumption and includes latched outputs with high current drive capability for directly driving LEDs. It .D an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller. also possesses Byw sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming w data on its ports without having to communicate via the I C-bus. This means that the INF8574 can remain a 2 2 2 U 4 t m o .
