At Distance 1/16 ± 1/32 Inch (1.59mm ± 0.79mm) from case for 10s MaximumDescriptionCD4048BMS 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 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:
