74ABT374A
Octal D-type flip-flop; positive-edge trigger (3-State)
The 74ABT374A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT374A is an 8-bit, edge triggered register coupled to eight 3-State output buffers. The two sections of the device are controlled independently by the clock (CP) and Output Enable (OE) control gates.
The register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop?s Q output.
The 3-State output buffers are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. The active-Low Output Enable (OE) controls all eight 3-State buffers independent of the clock operation.
When OE is Low, the stored data appears at the outputs. When OE is High, the outputs are in the High-impedance 'OFF' state, which means they will neither drive nor load the bus.
