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 CD4514BC and CD4515BC 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.
