SPI Interface, 4 Ω RON, ±15 V/+12 V/±5 V, 1.8 V Logic Control, 8:1/Dual 4:1 Muxes ADGS1408/ADGS1409
FEATURES
SPI interface with error detection Includes CRC, invalid read/write address, and SCLK count error detection Supports burst mode and daisy-chain mode Industry-standard SPI Mode 0 and SPI Mode 3 interface compatible
Round robin mode allows switching times comparable with a parallel interface
General-purpose digital outputs to control other devices, such as parallel switches from Analog Devices, Inc.
