Small 37.9 KB PDF for the 74HC4050, a hex non-inverting buffer from the high-speed CMOS family, often used as a level shifter because its inputs can accept voltages above its supply. The name gives no manufacturer, and the extra token in it carries no clear meaning. As a component reference it provides pinout and electrical limits for tracing buffered signals between sections of a board. Confirm the exact marking on the chip, as the similar 4050 and 4049 parts differ in function, the latter being inverting.
