WebHigh TTL values are typically used for records that rarely change, such as MX or TXT records. Longer TTLs reduce resolution times since every time an authoritative nameserver provides an answer to a query, it results in an additional lookup. A high TTL provides faster responses for more static resources by storing the information locally before ...

Read as Output = Inverted Input if Enable is NOT equal to “1”. An Active-low Inverting Tri-state Buffer is the opposite to the above as its output is enabled or disabled when a logic level “0” is applied to its “ enable ” control line. When a buffer is enabled by a logic “0”, the output is the complement of its input.
