Yes that's the beasties. They were rather nifty when compared with the effort needed to achieve the same result with discrete transistors and a voltage-divider network.
I remember that you could even at one time buy those DIL "Bar-graph" LEDs which had the first 6 or 7 LEDs green, then a couple of orange and finally one red, specifically for use with the 3914/3915 chips.
