PCA9554A |
| Part Number | PCA9554A |
| Manufacturer | Texas Instruments |
| Title | Remote 8-Bit I2C and SMBus I/O Expander |
| Description | 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. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data (SDA)]. The PCA9554A consists of one 8-bit Configur. |
