Texas Instruments Incorporated (Texas Instruments) has introduced two new ceramic-packaged transceivers, SN65HVD11SJD 3.3-V single, half-duplex RS-485 transceiver, and the SN65HVD233SJD 3.3-V CAN transceiver. These devices enable communication in high-temperature applications. These devices feature no thermal shutdown and meet the demanding requirements of oil exploration applications, such as downhole drilling.
These new transceivers are the first two parts to be released from the company in a complete signal chain roadmap for high-temperature industrial and aviation electronics applications. Future products will include data acquisition, processing and data transmission devices. Devices in the portfolio operate in an extended temperature range of -55C to 210C and have a targeted lifetime of 1000 hours.
