11C06

750 MHz D-Type Flip-Flop

General Description

The 11C06 is a high-speed ECL D-Type Master-Slave Flip-

Flop capable of toggle rates over 750 MHz Designed pri-

marily for high-speed prescaling it can also be used in any

application which does not require preset inputs The circuit

is voltage-compensated which makes input thresholds and

Q and Q outputs are provided as are two Data inputs Clock

and Clock Enable inputs The 11C06 is pin-compatible with
