CMOS (Complementary Metal-Oxide-Semiconductor) is a type of semiconductor technology known for low power consumption, whereas TTL (Transistor-Transistor Logic) is a class of digital circuits built from bipolar junction transistors, consume high power. ...

Theadvantage of the CMOS over the TTL chipsis that the CMOS has a higherdensity of logic gateswithin the same material. TTL chipsconsume more poweras compared tothe powerconsumed by the CMOS chips even at rest. The power consumption of the CMOS depends on various factors and is variable. T...
Input buffer for translating TTL levels to CMOS levelsPerry W Lou
A: Switches, such as the ADG9xx family of parts, have an integrated TTL driver that allows easy interfacing with other CMOS devices, since CMOS is compatible with LVTTL logic levels. The small size of devices with integrated drivers is a solution for many space-constrained applications....
A CMOS integrated circuit is made compatible with TTL input signals. A regulator operates the CMOS gates in an array at a voltage that is slightly lower than the supply. The regulator sense circuit is made responsive to an operating gate and to a TTL bias reference. Accordingly, the regulator...

Conversely, a TTL low - voltage level disables the amplifier, which reduces the supply current from 8.3 mA to 3.4 μA per amplifier. This pin voltage is referenced to a single-supply ground. When using a split-supply, such as ±2.5 V, the enable and disable voltage levels are referenced...
