The 16-bit wide UT54ACTQ16374 D flip-flop is built using Aeroflex's Commercial RadHardTM epitaxial CMOS technology and is ideal for space applications. This high-speed, low power 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 drivers and working registers. Each flip-flop will store the state of their indivdual D inputs (In) that meet the setup and hold requirements on the low-to-high clock (CPn) transition. With the Output Enable (OEn) low, the contents of the flip-flops are available 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.
