4位透明锁存器/ 4至16线译码器 4−Bit Transparent Latch / 4−to−16 Line Decoder
The MC14514B and MC14515B are two output options of a 4 to 16 line decoder with latched inputs. The MC14514B output active high option 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 to 16 line decoder are constructed with N−channel and P−channel enhancement mode devices in a single monolithic structure. The latches are R−S type flip−flops and data is admitted upon a signal incident at the strobe input, decoded, and presented at the output.
