MC10231 High Speed Dual Type D Master-Slave Flip-Flop

The is a dual master­slave type D flip­flop. Asynchronous Set (S) and Reset (R) override Clock (CC) and Clock Enable (CE) inputs. Each flip­flop may be clocked separately by holding the common clock in the low state and using the enable inputs for the clocking function. If the common clock to be used to clock the flip­flop, the Clock Enable inputs must be in the low state. In this case, the enable inputs perform the function of controlling the common clock. The output states of the flip­flop change on the positive transition of the clock. A change in the information present at the data (D) input will not affect the output information at any other time due to master­slave construction. 270 mW typ/pkg (No Load) tpd 2 ns typ tTog = 225 MHz typ tr, 2.0 ns typ (20%­80%)

CE + CC. A clock is a clock transition from a low to a high state.

Pin assignment is for Dual­in­Line Package. For PLCC pin assignment, see the Pin Conversion Tables on page 18 of the ON Semiconductor MECL Data Book (DL122/D).

Each MECL 10,000 series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The circuit in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear fpm is maintained. Outputs are terminated through a 50­ohm resistor to ­2.0 volts. Test procedures are shown for only one gate. The other gates are tested in the same manner.
