PCF8574AN - IC, I2C BUS EXPANDER 16DIP

PCF8574AN - IC, I2C BUS EXPANDER 16DIP Descrição geral do produto This 8 bit input/output expander for the two line bidirectional bus (I2C) is designed for 2.5V to 6V VCC operation. The PCF8574AN provides general purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data (SDA)]. The device features an 8 bit quasi-bidirectional I/O port (P0-P7), including latched outputs with high current drive capability for directly driving LEDs. Each quasi-bidirectional I/O can be used as an input or output without the use of a data direction control signal. At power on, the I/Os are high. In this mode, only a current source to VCC is active. An additional strong pull-up to VCC allows fast rising edges into heavily loaded outputs. This ...

PCF8574AN - IC, I2C BUS EXPANDER 16DIP

Descrição geral do produto

This 8 bit input/output expander for the two line bidirectional bus (I2C) is designed for 2.5V to 6V VCC operation. The PCF8574AN provides general purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data (SDA)]. The device features an 8 bit quasi-bidirectional I/O port (P0-P7), including latched outputs with high current drive capability for directly driving LEDs. Each quasi-bidirectional I/O can be used as an input or output without the use of a data direction control signal. At power on, the I/Os are high. In this mode, only a current source to VCC is active. An additional strong pull-up to VCC allows fast rising edges into heavily loaded outputs. This device turns on when an output is written high and is switched off by the negative edge of SCL. The I/Os should be high before being used as inputs.

Low standby current consumption of 10mA max.
Compatible with most microcontrollers
Latched outputs with high current drive
I2C to parallel port expander capability for directly driving LEDs
Open-drain interrupt output
Latch-Up performance exceeds 100mA Per JESD 78, Class II
