The Intersil ACTS74MS is a radiation hardened Dual D flip-flop with Set(s) and Reset (R). The logic level at data input is transferred to the output during the positive transition of the clock. The Set and Reset are independent from the clock and accomplished by a low level on the appropriate input. The ACTS74MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of the radiation hardened, high-speed, CMOS/SOS logic family. The ACTS74MS is supplied in a 14-lead Ceramic Flatpack (K suffix) or a 14-lead Ceramic Dual-In-Line package (D suffix).
