DESCRIPTION
The LVT534 is a high-performance BiCMOS product designed for
V
CC
operation at 3.3V.
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 (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.
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.
