Which of the following statements is incorrect?
1
TTL logic has very low power consumption and is therefore widely used in highly integrated components
2
TTL devices have logic levels of about 3.4 V and 0.2 V
3
TTL logic normally operates from a single 5 V supply
4
Standard TTL devices have a propagation delay that is dominated by the storage time of the bipolar transistors used
