GENERAL DESCRIPTION
This RPROM is capable of operating at speeds as fast as 35 ns address access time, which enables it to be used directly with today's fast microprocessors and DSP processors without introducing any wait states. All inputs and outputs are TTL compatible. The WS57C71C is a low power device even when operated at its fastest speed. The DIP version is packaged in a 300 mil wide DIP package saving board space for the user.
