CD4514BC CD4515BC 4-Bit Latched/4-to-16 Line Decoders October 1987 Revised January 2004 CD4514BC CD4515BC 4-Bit Latched/4-to-16 Line Decoders General Description The CD4514BC and CD4515BC are 4-to-16 line decoders with latched inputs implemented with complementary MOS (CMOS) circuits constructed with N- and P-channel enhancement mode transistors. These circuits are primarily used in decoding applications where low power dissipation and/or high noise immunity is required. The CD4514BC (output active high option) presents a logical “1” at the selected output, whereas the CD4515BC presents a logical “0” at the selected output. The input latches are R–S type flip-flops, which hold the last input data presented prior to the strobe transition from “1” to “0”. This input data is decoded and the corresponding output is activated. An output inhibit line is also available.
