AMD Fairchild Harris Intel Motorola/Freescale QML Raytheon SigneticsSignetics - Low Power Schottky TTL 54LS00 - 74LS00
The Series 54LS/74LS Schottky TTL family features both Schottky-barrier-diode inputs and emitter inputs and utilizes full Schottky-barrier-diode clamping to achieve speeds comparable to Series 54/74 at one-fifth of the power. They retain the desirable features of, and are completely compatible with, most of the popular saturated logic circuits.
