*** Source Electronics: IC I/O EXPANDER I2C 8B 16SOIC

***OMO Electronic: This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation. The device provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) and serial data (SDA)].

***AS USD: The PCA9557 consists of one 8-bit configuration (input or output selection), input port, output port, and polarity inversion (active-high) registers. At power on, the I/Os are configured as inputs. However, the system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding input or output register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master.

***AS INTRUMENTS: The device outputs (latched) have high-current drive capability for directly driving LEDs. The device has low current consumption.

***as Instruments (TI): The system master can reset the PCA9557 in the event of a timeout or other improper operation by asserting a low in the active-low reset (RESET) input. The power-on reset puts the registers in their default state and initializes the I2C/SMBus state machine. Asserting RESET causes the same reset/initialization to occur without depowering the part.

***AS INSTR: Three hardware pins (A0, A1, and A2) are used to program and vary the fixed I2C address, allowing up to eight devices to share the same I2C bus or SMBus.

PCA95xx I²C, SMBus Repeaters, Switches, Expanders: OMO Electronic PCA95xx I²C and SMBus devices consist of a variety of logic ICs, including repeaters, bidirectional translating switches, and I/O expanders. The TI PCA9515A dual bidirectional I²C and SMBus repeater is a BiCMOS IC intended for I²C and SMBus systems applications. The PCA9515A contains two identical bidirectional open-drain buffer circuits that enable I²C and similar bus systems to be extended without degradation of system performance. The TI PCA9544A and PCA9545A are quad bidirectional translating switches controlled via the I²C bus. The SCL/SDA upstream pair on the PCA9544A and PCA9545A fans out to four downstream pairs, or channels On the PCA9544a, one SCL/SDA pair can be selected at a time, and this is determined by the contents of the programmable control register. On the PCA9545A, any individual SCn/SDn channel or combination of channels can be selected, and this is determined by the contents of the programmable control register. The TI PCA9554A and PCA9557 are remote 8-bit I²C and SMBus expanders. The PCA9554A and PCA9557 provide general-purpose I/O expansion for most microcontroller families via the I²C interface.Learn More
