[Omnirel] DESCRIPTION The OM955X series of Switching Regulators are designed for pin compatibility with standard 3- Pin linear regulators. They are well suited for on-board, non- isolated power applications where efficient point- of- load regulation is needed. The package is designed using Chip-

8-bit I2C and SMBus I/O port with interrupt

DESCRIPTION The PCA9554 and PCA9554A are 16-pin CMOS devices that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C/SMBus applications and were developed to enhance the Philips family of I C I/O expanders. The improvements include higher drive capability, 5V I/O t
