Description

The IRFF310 are ultra-fast ECL comparators capable of very short propagation delays. Their design maintains the excellent DC matching characteristics normally found only in slower comparators.

The IRFF310 have differential inputs and complementary outputs that are fully compatible with ECL-logic levels. Output current levels are capable of driving 50 terminated transmission lines. The ultra-fast operation makes signal processing possibleat frequencies in excess of 600MHz.

The IRFF310 feature a latch-enable (LE) function that allows the comparator to be used in a sample-hold mode. When LE is ECL high, the comparator functions normally. When LE is driven ECL low, the outputs are forced to an unambiguous ECL-logic state,dependent on the input conditions at the time of the latch input transition. If the latch-enable function is not used on either of the two comparators, the appropriate LE input must be connected to ground; the companion LE input must be connected to a high ECL logic level.

These devices IRFF310 are available in SO, QSOP, and tiny MAX packages for added space savings.
