PCF8575RGER Datasheet PDF - TI

The PCF8575RGER is a 16-bit I/O Expander for the two-line bidirectional bus (I²C) is designed for 2.5 to 5.5V VCC operation. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I²C interface [serial clock (SCL), serial data (SDA)]. The device features a 16-bit quasi-bidirectional input/output (I/O) port (P07-P00, P17-P10), 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.

● Open-drain interrupt output

● Compatible with most microcontrollers

● 400kHz Fast I²C bus

● Address by 3 hardware address pins for use of up to 8 devices

● Latched outputs with high-current drive capability for directly driving LEDs

● Current source to VCC for actively driving a high at the output

● Latch-up performance exceeds 100mA per JESD 78, class II

● 10µA Maximum low standby-current consumption

● Green product and no Sb/Br

●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
