	The original 74 series chips (which have numbers of the form '74xx') were joined over time by many other compatible families. '74H' used more power, but were faster; '74L' use less, and were slower. '74S' (using Schottky circuits) which were faster followed, along with '74LS' (low-power Schottky), not as fast as 74S, but using less power.
