Philips PCA9554PW 8-bit I2C and SMBus I/O port with interrupt 184.25Kb, 20 pg.
TI PCA9554PWG4 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 PCA9554 consists of one 8-bit Configuration (input or output selection), Input, Output, and Polarity Inversion (active high or active low) registers. At power on, the I/Os are configured as inputs withA weak pullup to VCC. However, the system master c 309.34Kb, 28 pg.
