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

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
