CD4093B datasheet in PDF format, about 575 KB, covering the CMOS quad two-input NAND gate with Schmitt-trigger inputs. Expect the pinout, input hysteresis data, propagation delays and supply limits. On the bench it is used to identify gate inputs and outputs, confirm that noisy or slow signals are being squared up correctly, and build simple test oscillators. The same document helps cross-reference HEF4093 and HCF4093 versions, which typically share the pinout.
