The 555 timer already in the catalog covers a huge range of timing and oscillator jobs on its own, but plenty of projects need two of those functions running independently, one timer generating a clock signal while another handles a separate delay or pulse-width job. The NE556 solves that by packing two complete, independent 555-style timer circuits onto a single chip, saving board space and wiring over using two separate 555 chips side by side.
