The input threshold is relatively stable under varying tempera-ture conditions, but will scale with changes in VCC. Figure 2. Input Threshold Voltage Level on 3.3 Volt Logic Relative to Vcc When operating with Vcc at 2.7 volts, the input thresholdThe differing voltage level requirements of TTL and CMOS technology present problems when the two types of gates are used in the same system. Although operating CMOS gates on the same 5.00 volt power supply voltage required by the TTL gates is no problem, TTL output voltage levels will not be compatible with CMOS input voltage requirements.For any logic family, there are a number of threshold voltage levels to know. Below is an example for standard 5V TTL levels: V OH-- Minimum OUTPUT Voltage level a TTL device will provide for a HIGH signal. V IH-- Minimum INPUT Voltage level to be considered a HIGH. V OL-- Maximum OUTPUT Voltage level a device will provide for a LOW signal.

The need for logic voltage level translation is prevalent on most electronic systems today. For example, . Since 5-V TTL and 3-V LVTTL/LVCMOS switching thresholds are equal (see Figure 1), devices with inputs sized to accept 5-V TTL signals (at V CC =5 V) can be used to translate from 3.3 V to 5 V. This is a simple way of up-translating from .
The use of either the higher or the lower voltage level to represent either logic state is arbitrary. The two options are active high (positive logic) and active low (negative logic).Active-high and active-low states can be mixed at will: for example, a read only memory integrated circuit may have a chip-select signal that is active-low, but the data and address bits are conventionally .

Abstract. Regional left ventricular (LV) systolic dysfunction has been identified in diastolic heart failure (DHF). However, the relationship between regional or global LV systolic function and heart failure symptoms in DHF has not been evaluated in detail.Es gilt als schlechtes Maß für die systolische Funktion. Es ist nur dann zuverlässig, wenn der linker Ventrikel eine normale Geometrie und keine signifikanten Wandbewegungsstörungen aufweist. Die fraktionierte Verkürzung kann im M-Mode und 2D gemessen werden. FS = (LVEDD – LVESD)/LVEDD.
