Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge... Read More | |
| Logic | 3 | 1 | Each circuit functions as a NAND gate or inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and for negative-going (VT-) signals. The hysteresis or backlash, which is the difference between the two threshold levels (VT+- VT-), is typically 800 millivolts. These circuits... Read More | |
