This TTL shield with high level logic is from the LM111's own 80's manual. The integrated circuit is no longer easily found, but the circuit can be adapted to use modern equivalent operational amplifiers.
This circuit is from a 1978 optoelectronics manual from Texas Instruments. The transistor can be a...
This inverter can reach a power of 300 W depending on the transformer used. In this case, a...
This circuit uses an LM3900 transconductance operational amplifier to generate pulses whose...
