PI4IOE5V9555LEX

PI4IOE5V9555 16-Bit I2C-Bus and SMBus I/O Port with Interrupt Features Description  Operation Power Supply Voltage from 2.3V to 5.5V The PI4IOE5V9555 is an I2C-bus I/O expander that provides 16-bits of general purpose parallel input/output (GPIO) expansion for I2C-bus/SMBus applications. Its features include a higher driving capability, 5V tolerance, lower power supply, individual I/O configuration, and smaller packaging. It provides a simple solution when an additional I/O is required for ACPI power switches, sensors, push buttons, LEDs, fans, etc.  16-bit I/O pins which can be programmed as Input or Output  5V Tolerant I/Os  Polarity Inversion Register  Active LOW Interrupt Output  Low Current Consumption  0Hz to 400KHz Clock Frequency The PI4IOE5V9555 consists of two 8-bit configuration registers to configure the I/Os as either inputs or outputs, and two 8-bit polarity registers to change the polarity of the input port register data. The data for each input or output is kept in the corresponding input port or output port register. All registers can be read by the system master.  Noise Filter on SCL/SDA Inputs  Power-On Reset  ESD Protection (4KV HBM and 1KV CDM)  Latch-Up Tested (Exceeds 100mA)  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3)  For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ The PI4IOE5V9555 open-drain interrupt output is activated and indicates to the system when any input state has changed. The power-on reset sets the registers to their default values and initializes the device state machine. Three input pins (A0, A1, A2) can select the I2C-bus address of PI4IOE5V9555 from the eight preset address. It allows up to eight PI4IOE5V9555 to share the same I2C-bus/SMBus and provide maximum 128 I/Os.  Offered in Two Different Packages: TSSOP-24 and TQFN 4x4-24 Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2.
