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 RS type flipflops which hold the last input data presented prior to the strobe transition from "1" to "0". These high and low options of a 4bit latch/4 to 16 line decoder are constructed with Nchannel and Pchannel enhancement mode devices in a single monolithic structure. The latches are RS type flipflops 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.
