LS-TTL Compatible

For digital input circuits, a logic 1 is obtained for inputs of 2.0 to 5.5 V which can source 20 µA, and a logic 0 is obtained for inputs of 0 to 0.8 V which can sink 400 µA. For digital output signals, a logic 1 is represented by 2.4 to 5.5 V with a current source capability of at least 400 µA; and a logic 0 is represented by 0 to 0.6 V with a current sink capability of at least 16 MA. "LS" stands for low-power Schottky. LS-TTL Unit Load: A load with LS-TTL voltage levels, which will draw 20 µA for a logic 1 and -400 µA for a logic 0. LSD (Least-Significant Digit): The rightmost active (non-dummy) digit of the display. LVDT - Linear Variable Differential Transformer
