DESCRIPTION
The 16-bit wide UT54ACTQ16374 D flip-flop is built using
Aeroflex’s Commercial RadHard^TM epitaxial CMOS technolo-
gy and is ideal for space applications. This high-speed, low pow-
er UT54ACTQ16374 D flip-flop is designed for bus oriented
applications. A buffered clock (CP) and Output Enable (OE) are
common to each byte and can be shorted together for full 16-bit
operation. The UT54ACTQ16374 are particularly suitable for
implementing buffer registers, I/O ports, bidirectional bus driv-
ers and working registers. Each flip-flop will store the state of
their indivdual D inputs (In) that meet the setup and hold re-
quirements on the low-to-high clock (CPn) transition. With the
Output Enable (OEn) low, the contents of the flip-flops are avail-
able at the output. When OEn is high, the outputs go to high
impedance state. Operation of OEn input does not affect the state
of the D flip-flops.
