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.
