BCD-to-7 Segment Decoder
General Description
The MM54C48 MM74C48 BCD-to-7 segment decoder is a
monolithic complementary MOS (CMOS) integrated circuit
constructed with N- and P-channel enhancement transis-
tors Seven NAND gates and one driver are connected in
pairs to make binary-coded decimal (BCD) data and its com-
plement available to the seven decoding AND-OR-INVERT
gates The remaining NAND gate and three input buffers
provide test-blanking input ripple-blanking output and rip-
ple-blanking inputs
