The HM7630101LFJTR is a radiation-tolerant, low-power octal line driver IC from the EVAL-LS family of line driver ICs manufactured by TT Electronics. The device has eight differential outputs, each of which has a voltage swing of 3 to 5.5 V. The device has an upstream channel, which can be driven by either an AVCC rail or a logic voltage rail. The main features of the IC include 8-channel differential output driver, a -40°C to +125°C temperature range, an industrial temperature range of -40°C to +85°C, and radiation tolerance of up to 200 Krad (Si) of total ionizing dose (TID). The IC is suitable for aerospace, automotive, and space applications that require radiation-tolerant operation.
