CD4514BC CD4515BC
4-Bit Latched/4-to-16 Line Decoders
General Description
The CD4514BC and CD4515BC are 4-to-16 line decoders
with latched inputs implemented with complementary MOS
(CMOS) circuits constructed with N- and P-channel
enhancement mode transistors. These circuits are prima-
rily used in decoding applications where low power dissipa-
tion and/or high noise immunity is required.
The CD4514BC (output active high option) presents a logi-
cal “1” at the selected output, whereas the CD4515BC pre-
sents a logical “0” at the selected output. The input latches
are R–S type flip-flops, which hold the last input data pre-
sented prior to the strobe transition from “1” to “0”. This
input data is decoded and the corresponding output is acti-
vated. An output inhibit line is also available.
