I was looking at this Texas Instruments datasheet and saw this scheme:
Could anybody tell me what kind of transistors are on the left side of the diagram? I have never seen that symbol before, nor can I find any information on it.

The circuit utilizes Schottky transistors as opposed to normal BJTs. Note that the title of the diagram is "LS04" where LS = low-power-schottky. From the wiki page quoted, a Schottky transistor is like this: -
Effective internal circuit composed of Schottky diode and bipolar junction transistor.
Another quote: -
A Schottky transistor is a combination of a transistor and a Schottky diode that prevents the transistor from saturating by diverting the excessive input current. It is also called a Schottky-clamped transistor.
