FIGURE 3.21 Maximum data rate vs. V EE.<br />

FIGURE 3.22 Power-delay products of multiplexers and demultiplexers.<br />

A 8:1 multiplexer and a 1:8 demultiplexer are designed in the same manner. In SPICE simulation, the<br />

power dissipation of the 8:1 multiplexer is 84 mW and that of the 1:8 demultiplexer is 136 mW, both<br />

from −2 V power supply at the same maximum operating speed. Figure 3.22 shows that the LV-ECL circuit<br />

exhibits the lowest reported power-delay products in both 4-bit and 8-bit multiplexers and demultiplexers.<br />
