Power-up clear circuitry having two thresholds |
摘要 |
Power-up clear circuitry includes a latch which powers-up in a preferred state. Threshold detect circuitry changes the state of the latch when the supply voltage reaches its operating value, and then switches itself off. Transient protection circuitry ensures that the latch properly powers-up in the preferred state after a supply transient which drops below the threshold voltage of the circuit devices.
