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 â1â at the selected output, whereas the MC14515B (output active low option) presents a logical â0â at the selected output. The latches are RâS type flipâflops which hold the last input data presented prior to the strobe transition from â1â to â0â.
These high and low options of a 4âbit latch / 4 to 16 line decoder are constructed with Nâchannel and Pâchannel enhancement mode devices in a single monolithic structure. The latches are RâS type flipâflops 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.
