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.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
