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 MB2377 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The MB2377 has two 8-bit, edge triggered registers, with individual D inputs and Q outputs. The common buffered clock (1CP or 2CP) input will load a set of eight flip-flops simultaneously when the corresponding Enable (1E or 2E) input is Low.

The registers of MB2377 are fully edge triggered. 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 nE inputs of MB2377 must be stable one setup time prior to the Low-to-High clock transition for predictable operation.
