MC14514B MC14515B
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.
These complementary circuits find primary use in decoding applications
where low power dissipation and/or high noise immunity is desired.
