DescriptionHCF4048B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. HCF4048B is an 8-input gate having four control inputs. Three binary control inputs Ka, Kb, and Kc provide the implementation of eight different logic functions. These functions are OR, NOR, AND, NAND, OR/AND, OR/NAND, AND/OR and AND/ NOR. A fourth control input Kd provides the user with a 3 state output. When control input Kd is high the output is either a logic 1 or a logic 0 depending on the inner states. When control input Kd is low, the output is an open circuit. This feature enables the user to connect this device to a common bus line. In addition to the eight input lines, an EXPAND input is provided that permits the user to increase the number of inputs to one HCF4048B. For example, two HCF4048Bs can be cascaded to provide a 16 input multifunction gate. When the EXPAND input is not used, it should be connected to VSS.
