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

The MAX9381 is offered in an 8-pin SO package and

the smaller 8-pin µMAX package.
