GaAs (gallium arsenide) ICs are simply ICs--not significantly different than TTL, CMOS, ECL, or other varieties of ICs. You normally choose ICs based on how well the functions, power requirements, size, and cost of a particular device fit a design requirement. The same is true for GaAs devices. Off-the-shelf digital GaAs ICs work well in communication applications and in designs that use 33-MHz and faster [micro processors]. GaAs chips have familiar IC functions, such as RAM and PLDs, and, most important, are not cost prohibitive as many people believe.
Certainly, generalizations, such as low power associated with CMOS or high speed associated with ECL, can ...
