74ABT574A
Datasheet
General description
The 74ABT574A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74ABT574A 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 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.
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.
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.
