UNISONIC TECHNOLOGIES CO., LTD U74LVC1G17 CMOS IC SINGLE SCHMITT-TRIGGER BUFFER 3 2 1 5 DESCRIPTION 4 The U74LVC1G17 is a single Schmitt-trigger buffer, it provides the function Y=A. The device have different input threshold levels for positive- going (VT+) and negative-going(VT-) signals because of the Schmitt-trigger action in the input. This device has power-down protective circuit, preventing device destruction when it is powered down.
