LT3000 series, LT4000 series and STC6000 series support special inputs and outputs in addition to standard I/O. These include High Speed Counter Input, Pulse Output, PWM Output, and Pulse Catch.
High Speed Counter Input: Can receive a pulse up to 100KHz (up to 50KHz for 2-Phase counter).
Pulse Output: LT4000 series can output a pulse up to 50 KHz. LT3000 series and STC6000 series can output a pulse up to 65 KHz.
PWM Output: Can output a pulse up to 65 KHz.
Pulse Catch: Can detect a pulse at 100 KHz (on for more than 5 microseconds).
Where and how to allocate I/O terminals differs between the standard I/O and special I/O.
