SN54LS48, BCD TO 7-SEGMENT DECODER

SN54/74LS48 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.

The circuit accepts 4-bit binary-coded-decimal (BCD) and, depending on the state of
