SK10E131

SK10/100E131 HIGH-PER.ORMANCE PRODUCTS Description The SK10E/100E131 is a Quad master-slave D-type flipflop with differential outputs. Each flip-flop may be clocked separately by holding Common Clock (CC) LOW and using the Clock Enable (CE*) inputs for clocking. Common clocking is achieved by holding the CE inputs LOW and using CC to clock all four flip-flops. In this case, the CE* inputs perform the function of controlling the common clock to each flip-flop. 4-Bit D .lip-.lop Features 1100 MHz Minimum Toggle Frequency Differential Outputs Individual and Common Clocks Individual Resets (asynchronous) Paired Sets (asynchronous) Extended 100E VEE Range of –4.2V to –5.5V 75KΩ Internal Input Pulldown Resistors Fully Compatible with MC10E131 and MC100E131 Specified Over Industrial Temperature Range: –40oC to 85oC ESD Protection of >4000V Available in 28-pin PLCC Package Individual asynchronous resets are provided (R). Asynchronous set controls (S) are ganged together in pairs, with the pairing chosen to reflect physical chip symmetry. Data enters the master when both CC and CE* are LOW, and transfers to the slave when either CC or CE (or both) go HIGH.
