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.


Description

The 74LVT543 is a high-performance BiCMOS product designed for VCC operation at 3.3V.

This device contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable (LEAB, LEBA) and Output Enable (OEAB, OEBA) inputs are provided for each register to permit independent control of data transfer in either direction. The outputs are guaranteed to sink 64mA.
