WebAug 16, 2024 · Time to Live (TTL) is a field on DNS records that controls how long each record is valid and — as a result — how long it takes for record updates to reach your end users. Longer TTLs speed up DNS lookups by increasing the chance of cached results, but a longer TTL also means that updates to your records take longer to go into effect. WebThe 74LS (Low-power Schottky) family (like the original) uses TTL (Transistor-Transistor Logic) circuitry which is fast but requires more power than later families. The 74 series is often still called the 'TTL series' even though the latest ICs do not use TTL! The 74HC family has High-speed CMOS circuitry, combining the speed of TTL with the very low power …
