SUMMARY
The discussion centers on the power consumption differences between Transistor-Transistor Logic (TTL) and Complementary Metal-Oxide-Semiconductor (CMOS) technologies. It is established that TTL consumes more power primarily due to its reliance on bipolar junction transistors (BJTs), which have higher static power consumption compared to CMOS's MOSFETs. The base-emitter diode drop in BJTs contributes significantly to this increased power usage. Additionally, the ON resistance of MOSFETs is generally lower than that of BJTs, further emphasizing the efficiency of CMOS technology.
