MAX9381 Overview

Lowest Power 3.0GHz ECL/PECL Differential Data and Clock D Flip-Flop

19-2397; Rev 0; 4/02
Lowest Power 3.0GHz ECL/PECL
Differential Data and Clock D Flip-Flop
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.
