PI4IOE5V9554/9554A 2 8-bit I C-Bus and SMBus I/O Port with Interrupt Features Description Operation Power Supply Voltage from 2.3V to 5.5 V 2 The PI4IOE5V9554 and PI4IOE5V9554A provide 8 bits of 8-bit I C-bus GPIO with Interrupt and Reset general purpose parallel input/output (GPIO) expansion for 5V Tolerant I/Os 2 I C-bus/SMBus applications. The device includes features Polarity Inversion Register such as higher driving capability, 5V tolerance, lower power Active LOW Interrupt Output supply, individual I/O configuration, and smaller packaging. It Low Current Consumption provides a simple solution when additional I/O is required for ACPI power switches, sensors, push buttons, LEDs, fans, etc. 0Hz to 400KHz Clock Frequency Noise Filter on SCL/SDA Inputs The PI4IOE5V9554/PI4IOE5V9554A consists of an 8-bit register to configure the I/Os as either inputs or outputs and Power-on Reset an 8-bit polarity register to change the polarity of the input ESD Protection (4KV HBM and 1KV CDM) port register data. The data for each input or output is kept in Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) the corresponding input port or output port register. All Halogen and Antimony Free. Green Device (Note 3) registers can be read by the system master. For automotive applications requiring specific change The PI4IOE5V9554/PI4IOE5V9554A open-drain interrupt control (i.e. parts qualified to AEC-Q100/101/200, PPAP output is activated and indicates to the system when any input capable, and manufactured in IATF 16949 certified state has changed. The power-on reset sets the registers to facilities), please contact us or your local Diodes their default values and initializes the device state machine. representative. 2 PI4IOE5V9554/9554A Pin Description Table 1: Pin Description Pin Name Type Description TSSOP16 TQFN16 1 15 A0 I Address Input 0 2 16 A1 I Address Input 1 3 1 A2 I Address Input 2 4 2 IO0 I/O Input/Output 0 5 3 IO1 I/O Input/Output 1 6 4 IO2 I/O Input/Output 2 7 5 IO3 I/O Input/Output 3 8 6 GND G Supply Ground 9 7 IO4 I/O Input/Output 4 10 8 IO5 I/O Input/Output 5 11 9 IO6 I/O Input/Output 6 12 10 IO7 I/O Input/Output 7 13 11 O Interrupt Output (Open Drain) INT 14 12 SCL I Serial Clock Line 15 13 SDA I Serial Data Line 16 14 VCC P Supply Voltage * I = Input O = Output P = Power G = Ground PI4IOE5V9554/ PI4IOE5V9554A www.diodes.com November 2019 Document Number DS40769 Rev 3 - 2 Diodes Incorporated 2
