HTL Encoder:

HTL stands for "High Threshold Logic." An HTL encoder is a type of digital encoder that uses a high voltage level as the logic high state. These encoders are commonly used in industrial applications for their robustness and reliability.

Difference Between HTL and TTL Encoder:

The main difference between HTL (High Threshold Logic) and TTL (Transistor-Transistor Logic) encoders lies in the voltage levels used to represent logic high and logic low states. HTL uses a higher voltage level for logic high compared to TTL, making it more suitable for industrial environments where noise immunity is crucial.
