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 RS 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.

Conditions

Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed. Except for "Operating Tempera-
ture Range" they are not meant to imply that the devices should be oper-
ated at these limits. The tables of "Recommended Operating Conditions"
and "Electrical Characteristics" provide conditions for actual device opera-
tion.
