CD4048BPW

LOGIC, 8IN GATE EXPND MULTI, 16TSSOP.

The CD4048BPW is a CMOS multifunction expandable 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 into a CD4048B. For example, two CD4048Bs can be cascaded to provide a 16-input multifunction gate. When the EXPAND input is not used, it should be connected to VSS.
