PDF reference for the CD4050, the CMOS hex non-inverting buffer, at 67.1 KB. Although classed as a schematic, it is probably a compact datasheet with pinout and electrical limits. The 4050 is popular as a down-level shifter because inputs can exceed its supply voltage, so this sheet helps when tracing signals between different logic voltages, verifying supply on the correct pins and testing each buffer stage. HCF4050 and HEF4050 parts are common equivalents.
