UNISONIC TECHNOLOGIES CO., LTD U74LVC3G17 CMOS IC TRIPLE SCHMITT-TRIGGER BUFFER DESCRIPTION The U74LVC3G17 is designed as three independent buffers with Schmitt-trigger action. it may have different input threshold levels for positive-going (VT+) and negative-going (VT−) signals. This device has power-down protective circuit, preventing device destruction when it is powered down. SOP-8 FEATURES * Wide supply voltage range from 1.65V to 5.5V * Inputs accept voltages up to 5.5V * IOFF supports partial-power-down mode * Low static power consumption; ICC=10μA (Max.)
