Dual octal D-type flip-flop with enable
MB2377
FEATURES
•
Ideal for addressable register applications
•
Two 8-bit positive edge-triggered registers
•
Two Enable inputs for address and data
synchronization applications
•
ESD protection exceeds 2000 V per MIL
STD 883 Method 3015 and 200 V per
Machine Model
2CP) input will load a set of eight flip-flops
simultaneously when the corresponding
Enable (1E or 2E) input is Low.
The registers 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 must be stable one setup time
prior to the Low-to-High clock transition for
predictable operation.
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

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.

NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
