4-Bit Latched4-to-16 Line Decoders

General Description

The CD4514B and CD4515B are 4-to-16 line decoders with

latched inputs implemented with complementary MOS

(CMOS) circuits constructed with N- and P-channel en-

hancement mode transistors These circuits are primarily

used in decoding applications where low power dissipation

andor high noise immunity is required

The CD4514B (output active high option) presents a logical

‘‘1’’ at the selected output whereas the CD4515B presents

a logical ‘‘0’’ at the selected output The input latches are

R – S type flip-flops which hold the last input data presented

prior to the strobe transition from ‘‘1’’ to ‘‘0’’ This input data

is decoded and the corresponding output is activated An

output inhibit line is also available
