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.
