General Description
The SY55851A is a highly flexible, universal logic gate
capable of up to 3.0GHz operation. This AnyGate
differential logic device will produce all possible logic
functions of two Boolean variables. It can be configured
as any of the following gates: AND, NAND, OR, NOR,
XOR, XNOR, DELAY, NEGATION (NOT). The
SY55851A can also function as a 2-input multiplexer.
The SY55851A has an output stage optimized for 50Ω loads.
