MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14514B MC14515B 4-Bit Transparent Latch/4-to-16 Line Decoder The MC14514B and MC14515B are two output options of a 4 to 16 line L SUFFIX decoder with latched inputs. The MC14514B (output active high option) CERAMIC CASE 623 presents a logical “1” at the selected output, whereas the MC14515B (output active low option) presents a logical “0” at the selected output. The latches are R–S type flip–flops which hold the last input data presented prior to the strobe transition from “1” to “0”. These high and low options of a 4–bit latch/4 P SUFFIX to 16 line decoder are constructed with N–channel and P–channel PLASTIC CASE 709 enhancement mode devices in a single monolithic structure. The latches are R–S type flip–flops and data is admitted
