CD4514BM/CD4514BC, CD4515BM/CD4515BC 4-Bit Latched/4-to-16 Line Decoders General Description Features The CD4514B and CD4515B 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 CD4514B (output active high option) presents a logical ‘‘1’’ at the selected output, whereas the CD4515B 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.

Therefore, all of the most significant bits from all of the registers can be transferred to the data bus before the next most significant bit is presented for transfer by the input registers. Information from the TRI-STATE bus is redistributed by the CD4514B 4-bit latch/decoder. Using the 4-bit address, INA – IND, the information on the inhibit line can be transferred to the addressed output line to the desired output registers, A – P. This distribution of data bits to the output registers can be made in many complex patterns. For example, all of the most significant bits from the input registers can be routed into output register A, all of the next most significant bits into register B, etc. In this way horizontal, vertical, or other methods of data slicing can be implemented. Two CD4512 8-channel data selectors are used here with the CD4514B 4-bit latch/decoder to effect a complex data routing system. A total of 16 inputs from data registers are selected and transferred via a TRI-STATEÉ data bus to a data distributor for rearrangement and entry into 16 output registers. In this way sequential data can be re-routed or intermixed according to patterns determined by data select and distribution inputs. Data is placed into the routing scheme via the 8 inputs on both CD4512 data selectors. One register is assigned to each input. The signals on A0, A1 and A2 choose 1-of-8 inputs for transfer out to the TRI-STATE data bus. A fourth signal, labelled Dis, disables one of the CD4512 selectors, assuring transfer of data from only one register. In addition to a choice of input registers, 1–16, the rate of transfer of the sequential information can also be varied. That is, if the CD4512 were addressed at a rate that is TL/F/5994 – 5 5 CD4514BM/CD4514BC, CD4515BM/CD4515BC 4-Bit Latched/4-to-16 Line Decoders Physical Dimensions inches (millimeters) Ceramic Dual-In-Line Package (J) Order Number CD4514BMJ, CD4514BCJ, CD4515BMJ or CD4515BCJ NS Package Number J24A Molded Dual-In-Line Package (N) Order Number CD4514BMN, CD4514BCN, CD4515BMN or CD4515BCN NS Package Number N24A LIFE SUPPORT POLICY NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF NATIONAL SEMICONDUCTOR CORPORATION.
