§ Low-power TTL (L), which traded switching speed (33ns) for a reduction in power consumption (1 mW) (now essentially replaced by CMOS logic)
§ High-speed TTL (H), with faster switching than standard TTL (6ns) but significantly higher power dissipation (22 mW)
§ Schottky TTL (S), introduced in 1969, which used Schottky diode clamps at gate inputs to prevent charge storage and improve switching time. These gates operated more quickly (3ns) but had higher power dissipation (19 mW)
§ Low-power Schottky TTL (LS)- used the higher resistance values of low-power TTL and the Schottky diodes to provide a good combination of speed (9.5ns) and reduced power consumption (2 mW), and PDP of about 20 pJ. Probably the most common type of TTL, these were used as glue logic in microcomputers, essentially replacing the former H, L, and S sub-families.
§ Fast (F) and Advanced-Schottky (AS) variants of LS from Fairchild and TI, respectively, circa 1985, with "Miller-killer" circuits to speed up the low-to-high transition. These families achieved PDPs of 10 pJ and 4 pJ, respectively, the lowest of all the TTL families.
§ Low-voltage TTL (LVTTL) for 3.3-volt power supplies and memory interfacing.

What is the family of cacti?
Cactaceae is the family of which all cactuses are members. The family is divided into four subfamilies. So cactuses may be further members of the Cactoideae, Maihuenioideae, Opuntioideae and Peraskioideae subfamilies. They then may be classified even further into a specific genus and species within each subfamily.

What is weapon of army ants?
The main weapons of all the army ants are their jaws, especially the very large jaws of the major soldiers. There are several subfamilies of army ants, and some of subfamilies have stings as well. Some of the African army ants do not have stings and others do. The American army ants (Eciton) all have stings.
What are the different types of language proof and logic solutions available for solving complex problems?
Different types of language, proof, and logic solutions for solving complex problems include formal logic, mathematical proofs, programming languages, and symbolic logic. These tools help break down problems into logical steps and provide a systematic approach to finding solutions.
