SN74S225 - 16 x 5 ASYNCHRONOUS FIRST-IN FIRST-OUT MEMORY
This 80-bit active-element memory is a monolithic Schottky-clamped transistor-transistor logic (STTL) array organized as 16 words by 5 bits.
A memory system using the SN74S225 easily can be expanded in multiples of 48 words or of 10 bits as shown in Figure 3.
The 3-state outputs controlled by a sing
