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 voltage ratings may be exceeded if the input and output current ratings are observed.


Description

The MB2543 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The MB2543 dual octal registered transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable (nLEAB, nLEBA) and Output Enable (nOEAB, nOEBA) inputs are provided for each register to permit independent control of data transfer in either direction. The outputs of MB2543 are guaranteed to sink 64mA.
