74F224 Description
This 64-bit active element First-In-First-Out (FIFO) is a monolithic Schottky-clamped transistor-transistor logic (STLL) array organized as 16 words of 4-bits each. A memory system using the 74F224 can be easily expanded in multiples of 15m+1 words or of 4n bits, or both (where n is the number of packages in the horizontal array). However, an external gating is required (see Figure 1).
