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 also function as a 2-input multiplexer. The SY55851 has an output stage optimized for 100Ω loads, and the SY55851A is optimized for 50Ω loads. The differential inputs for both devices are normally terminated with a single resistor (100Ω) between the true and complement pins. APPLICATIONS s ...
