Support is limited to customers who have already adopted these products. The Intersil HCS374MS is a Radiation Hardened non-inverting octal D-type, positive edge triggered flip-flop with three-stateable outputs. The HCS374MS utilizes advanced CMOS/SOS technology. The eight flip-flops enter data into their registers on the LOW-to-HIGH transition of the clock (CP). Data is also transferred to the outputs during this transition. The output enable (OE) controls the three-state outputs and is independent of the register operation. When the output enable is high, the outputs are in the high impedance state. The HCS374MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family. The HCS374MS is supplied in a 20 lead Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
