Description
The Intersil HCTS374MS is a Radiation Hardened non-inverting
octal D-type, positive edge triggered flip-flop with three-stateable
outputs. The eight flip-flops enter data into their registers on the
LOW-to-HIGH transition of the clock (CP). Data is also trans-
ferred 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 HCTS374MS 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 HCTS374MS is supplied in a 20 lead Ceramic flatpack (K
suffix) or a SBDIP Package (D suffix).
