Q. What should be done to unused inputs on TTL gates? (Solved)
1. they should be left disconnected so as not to produce a load on any of the other circuits and to minimize power loading on the voltage source.
2. all unused gates should be connected together and tied to v through a 1 k resistor.
3. all unused inputs should be connected to an unused output; this will ensure compatible loading on both the unused inputs and unused outputs.
4. unused and and nandinputs should be tied to vccthrough a 1 k resistor; unused or and norinputs should be grounde
- d. unused and and nandinputs should be tied to vccthrough a 1 k resistor; unused or and norinputs should be grounded.
