What should be done to unused inputs on TTL gates? |
| A. | 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. |
| B. | All unused gates should be connected together and tied to V< sub=""> through a 1 k resistor.<> |
| C. | All unused inputs should be connected to an unused output; this will ensure compatible loading on both the unused inputs and unused outputs. |
| D. | Unused AND and NAND inputs should be tied to VCC through a 1 k resistor; unused OR and NOR inputs should be grounded. |
