MAX9381ESA+T

P1-P3P4-P6P7-P7
General Description
The MAX9381 differential data, differential clock D flip-
flop is pin compatible with the ON Semiconductor
MC100EP52, with the added benefit of a wider supply-
voltage range from 2.25V to 5.5V and 25% lower supply
current. Data enters the master part of the flip-flop
when the clock is low and is transferred to the outputs
upon a positive transition of the clock. Interchanging
the clock inputs allows the part to be used as a nega-
tive edge-triggered device. The MAX9381 utilizes input
clamping circuits that ensure the stability of the outputs
when the inputs are left open or at V
EE
.
The MAX9381 is offered in an 8-pin SO package and
the smaller 8-pin µMAX package.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” 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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
