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. ...

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. GaAs ...
Applying TTL levels to a 5V switch, however, can cause the supply current to increase more than 1000 times. To avoid unnecessary power consumption, you should avoid TTL levels, which are simply a legacy of the 1980s. Signal HandlingFigure 3 also shows the value of RON versus signal voltage...

(SPDT) switch to fit into a miniscule 6-pin SOT23 package. Similarly, low-voltage dual-supply applications call for dual-supply switches. These switches require a V- pin in addition to the ground pin, and typically specify a logic interface with standard CMOS and TTL levels. The SPST MAX...

There is a substantial difference in the voltage level range for both. For TTL it is 4.75 V to 5.25 V while for CMOS it ranges between 0 to 1/3 VDD at a low level and 2/3VDD to VDD at high levels. CMOS technology ismore economicaland preferred more as compared to the TTL logic....
