Description

The Intersil ACS374MS is a radiation hardened octal D-type

flip-flop with three-state outputs. The eight edge-triggered flipflops 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 the

OEN is high, the outputs will be in the high impedance state.

The ACS374MS 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.
