Product data sheet
1. General description
The 74LVT574; 74LVTH574 is a high-performance product designed for VCC operation at
3.3 V.
This device 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 (pin CP) and output
enable (pin OE) control gates. The state of each D input (one setup time before the
LOW-to-HIGH clock transition) is transferred to the corresponding flip-flops 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 (pin OE) controls all eight 3-state buffers independent of
the clock operation.
When pin OE is LOW, the stored data appears at the outputs. When pin OE is HIGH, the
outputs are in the high-impedance OFF-state, which means they will neither drive nor load
the bus.
