MC14514B D

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.
1. Temperature Derating: Plastic “P and D/DW”
Packages: – 7.0 mW/_C From 65_C To 125_C
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
high−impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.

COMPLEX DATA ROUTING
times faster then the shift frequency of the input registers,
the most significant bit (MSB) from each register could be
selected for transfer to the data bus. Therefore, all of the
most significant bits from all of the registers can be
transferred to the data bus before the next most significant
bit is presented for transfer by the input registers.
Information from the 3−state bus is redistributed by the
MC14514B four−bit latch/decoder. Using the four−bit
address, D1 thru D4, the information on the inhibit line can
be transferred to the addressed output line to the desired
output registers, A thru P. This distribution of data bits to the
output registers can be made in many complex patterns. For
example, all of the most significant bits from the input
registers can be routed into output register A, all of the next
most significant bits into register B, etc. In this way
horizontal, vertical, or other methods of data slicing can be
implemented.
Two MC14512 eight−channel data selectors are used here
with the MC14514B four−bit latch/decoder to effect a
complex data routing system. A total of 16 inputs from data
registers are selected and transferred via a 3−state data bus
to a data distributor for rearrangement and entry into 16
output registers. In this way sequential data can be re−routed
or intermixed according to patterns determined by data
select and distribution inputs.
Data is placed into the routing scheme via the eight inputs
on both MC14512 data selectors. One register is assigned to
each input. The signals on A0, A1, and A2 choose one of
eight inputs for transfer out to the 3−state data bus. A fourth
signal, labelled Dis, disables one of the MC14512 selectors,
assuring transfer of data from only one register.
In addition to a choice of input registers, 1 thru 16, the rate
of transfer of the sequential information can also be varied.
That is, if the MC14512 were addressed at a rate that is eight
