TI introduces high-temperature transceivers for oil exploration equipment

Jan 21, 2012

DALLAS (Jan. 21, 2009) - Two new ceramic-packaged transceivers from Texas Instruments Incorporated (TI) (NYSE: TXN) enable communication in high-temperature applications. The devices feature no thermal shutdown, meeting the demanding requirements of oil exploration applications, such as downhole drilling. The SN65HVD11SJD 3.3-V single, half-duplex RS-485 transceiver and the SN65HVD233SJD 3.3-V CAN transceiver are the first two parts to be released from TI 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. For complete product information, please see www.ti.com/sn65hvd11sjd-pr and www.ti.com/sn65hvd233sjd-pr.
