Overview

SN74S225 16 × 5 ASYNCHRONOUS FIRST-IN, FIRST-OUT MEMORY WITH 3-STATE OUTPUTS SDLS207B – SEPTEMBER 1976 – REVISED APRIL 1998 D Independent Asychronous Inputs and Outputs D 16 Words by 5 Bits D DC to 10-MHz Data Rate D 3-State Outputs D Packaged in Standard Plastic 300-mil DIPs description 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 single output-enable (OE) input make bus connection and multiplexing easy.
