CD4048BM

Texas Instruments · Logic Gates · SOP-16

CD4048BM from Texas Instruments, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 J (OUTPUT) tri_state Three-state output that gives the selected logic function and goes open-circuit (high impedance) when Kd is low.
2 Kd input Three-state control input: high gives normal inverter action at the output, low makes the output open-circuit (high impedance), with input range -0.5 V to VDD+0.5 V.
3 H input Logic input H, with input voltage range -0.5 V to VDD+0.5 V.
4 G input Logic input G, with input voltage range -0.5 V to VDD+0.5 V.
5 F input Logic input F, with input voltage range -0.5 V to VDD+0.5 V.
6 E input Logic input E, with input voltage range -0.5 V to VDD+0.5 V.
7 Kb input Binary control input (with Ka and Kc) that selects one of eight logic functions, with input range -0.5 V to VDD+0.5 V.
8 VSS power_in Negative supply / ground reference, with all voltage ratings referenced to it.
9 Kc input Binary control input (with Ka and Kb) that selects one of eight logic functions, with input range -0.5 V to VDD+0.5 V.
10 Ka input Binary control input (with Kb and Kc) that selects one of eight logic functions, with input range -0.5 V to VDD+0.5 V.
11 D input Logic input D, with input voltage range -0.5 V to VDD+0.5 V.
12 C input Logic input C, with input voltage range -0.5 V to VDD+0.5 V.
13 B input Logic input B, with input voltage range -0.5 V to VDD+0.5 V.
14 A input Logic input A, with input voltage range -0.5 V to VDD+0.5 V.
15 EXPAND input Expand input that increases the number of gate inputs by cascading CD4048Bs, and is connected to VSS when not used.
16 VDD power_in Positive supply, recommended 3 V to 18 V, with an absolute maximum of -0.5 V to +20 V referenced to VSS.
