BCD TO 7-SEGMENT DECODER

The SN54 /74LS48 is a BCD to 7-Segment Decoder consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven decoding AND-OR-INVERT gates. The remaining NAND gate and three input buffers provide lamp test, blanking input/rippleblanking input for the LS48.

• Lamp Intensity Modulation Capability (BI/RBO)
• Internal Pull-Ups Eliminate Need for External Resistors
• Input Clamp Diodes Eliminate High-Speed Termination Effects
