MCM67J618B是Motorola发布的一款64K x 18 Bit BurstRAM Synchronous Fast Static RAM With Burst Counter and Registered Outputs。这是一款高性能、二次缓存内存,可用于i486和Pentium微处理器。
The MC74LVQ138 is a high performance, 1–of–8 decoder/ demultiplexer operating from a 2.7 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. The MC74LVQ138 is suitable for memory address decoding and other TTL level bus oriented applications.
