Texas Instruments has a wide portfolio of interface products to address multiple fieldbus and connectivity needs for I/O module designers. The ISO1176T, ISO35T and ISO3086T are a set of RS-485 transceivers with integrated transformer drivers. They use TI’s silicon integrated SiO2 capacitive isolation technology to meet various industry standards. The SN65HVS881, specifically designed for digital input modules, can take eight inputs from 0-34 V and serialize them to be transferred over the SPI bus. Up to 160 inputs can be cascaded in this way using multiple devices and reducing isolation costs. The TLK100 is an industrial Ethernet PHY from Texas Instruments. It has low latency and can support extended cable reach of up to 200m. It is IEEE802.3 compliant and enables cable diagnostics to detect breaks and damage.
