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 primarily

used in decoding applications where low power dissipation

and/or high noise immunity is required.

The CD4514BC (output active high option) presents a logical

“1” at the selected output, whereas the CD4515BC 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.
