Description
CD4048BMS is an 8-input gate having four control inputs. Three
binary control inputs - Ka, Kb, and Kc - provide the implementa-
tion 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
CD4048BMS (see Figure 2). For example, two CD4048BMS’s
can be cascaded to provided a 16-input multifunction gate. When
the EXPAND input is not used, it should be connected to VSS.
The CD4048BMS is supplied in these 16 lead outline packages:
