What are the advantages and disadvantages of transmission gate?

Transmission gates, which consist of complementary MOSFETs (n-channel and p-channel), offer several advantages, including low on-resistance and the ability to pass both high and low logic levels effectively. They also provide bidirectional signal flow, making them useful in analog and digital circuits. However, disadvantages include increased complexity in design and susceptibility to charge injection and clock feedthrough, which can affect signal integrity. Additionally, their performance can degrade at higher frequencies due to capacitive effects.
