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. OE 1 20 VCC Q0 2 19 Q7 D0 3 18 D7 D1 4 17 D6 Q1 5 16 Q6 Q2 6 15 Q5 D2 7 14 D5 D3 8 13 D4 Q3 9 12 Q4 10 11 CP GND Ordering Information
