Description
The Intersil ATCS374MS is a radiation hardened octal D-type
ï¬ip-ï¬op with three-state outputs. The eight edge-triggered ï¬ip-
ï¬ops enter data into their registers on the low to high transition of
clock (CP). The Output Enable (OEN) controls the three-state
outputs and is independent of the register operation. When OEN
is high, the outputs will be in the high impedance state.
The ACTS374MS 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.
