Description
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 technol-
ogy. 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 out-
puts 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).
