MC14514B, MC14515B

4-Bit Transparent

Latch/4-to-16 Line Decoder

The MC14514B and MC14515B are two output options of a 4 to 16

line decoder with latched inputs. The MC14514B (output active high

option) presents a logical “1” at the selected output, whereas the

MC14515B (output active low option) presents a logical “0” at the

selected output. The latches are R–S type flip–flops which hold the

last input data presented prior to the strobe transition from “1” to “0”.

These high and low options of a 4–bit latch/4 to 16 line decoder are

constructed with N–channel and P–channel enhancement mode

devices in a single monolithic structure. The latches are R–S type

flip–flops and data is admitted upon a signal incident at the strobe

input, decoded, and presented at the output.

These complementary circuits find primary use in decoding

applications where low power dissipation and/or high noise immunity

is desired.

This device contains protection circuitry to guard against damage due to high

static voltages or electric fields. However, precautions must be taken to avoid

applications of any voltage higher than maximum rated voltages to this

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
