These include the 74LS244 and the 74LS367. When selecting a buffer, there are two parameters to watch for. The first is the output edge rate. If it is too fast,. In computer systems it is necessary to provide a substantial amount of memory. If a system is implemented using FPGA technology it is possible to provide some A | Page 10 of 12. 8-Bit Processors. The circuit of Figure 13 shows the general principles for connecting the AD394 to an 8-bit data bus. The 74LS244 buffers.
