SY55851 - Micrel Semiconductor

SY55851 3.0GHz CML AnyGate ANY LOGIC

The SY55851 and SY55851A are highly flexible, universal logic gates capable of up to 3.0GHz operation (SY55851A). These AnyGate® differential logic devices will produce all possible logic functions of two Boolean variables. They can be configured as any of the following gates: AND, NAND, OR, NOR, XOR, XNOR, DELAY, NEGATION (NOT). The SY55851 and SY55851A can.
