    I'm currently doing a report which will be submitted 1 day from now! kindly give me some codes for downloading Schottky transistor-transistor logic (STTL) in LTSPICE! I need it badly! Please! Thank you!

    In Schottky TTL the low cut-in voltage of the diode limits the base-collector voltage to about 400 mV, which prevents the transistor falling into saturation. This results in faster switching times for the transistors constructed in this way.

    Just adding the schottky diode to a transistor found in Spice as described above should let you see the effects it creates.
