SEMICONDUCTOR TECHNICAL DATA
The MC10EL/100EL31 is a 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 which require the ultimate in AC performance. Both set and reset inputs are asynchronous, level triggered signals. Data enters the master portion of the flip-flop when clock is LOW and is transferred to the slave, and thus the outputs, upon a positive transition of the clock.

Frequently Asked Questions
What is the primary mechanism for transferring data to the outputs?
Data enters on low clock and transfers upon a positive transition of the clock signal.
How does this device compare to older chips like the E131?
It is functionally equivalent to the E131 but offers significantly higher performance capabilities, particularly in AC applications.
What is the maximum operating speed (toggle frequency)?
The device has a maximum toggle frequency up to 2.8 GHz at an ambient temperature of 85°C.
Does the chip include protection against electrical surges?
Yes, it features internal ESD Protection rated above 1000V.
