DESCRIPTION
The AZ10/100EL31 is a master-slave D flip-flop with set and reset. The device is functionally equivalent to the
E131 device with higher performance capabilities. With propagation delays and output transition times significantly
faster than the E131, the EL31 is ideally suited for those applications that require the ultimate in AC performance.
Both set and reset inputs are asynchronous, level triggered signals. Data enters the master section of the flip-
flop when the clock is LOW. When the clock transitions from LOW to HIGH, the data in the master section
transfers into the slave section and through to the outputs.
NOTE: Specifications in ECL/PECL tables are valid when thermal equilibrium is established.
