NSC CD4514BC 4-bit latched/4-to-16 line decoder Datasheet

CD4514BM/CD4514BC, CD4515BM/CD4515BC
4-Bit Latched/4-to-16 Line Decoders
General Description
Features
The CD4514B and CD4515B 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 CD4514B (output active high option) presents a logical
‘‘1’’ at the selected output, whereas the CD4515B 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.

*AC Parameters are guaranteed by DC correlated testing.
Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits. The tables of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provide conditions for actual device operation.
Note 2: VSS e 0V unless otherwise specified.
Note 3: IOH and IOL are tested one output at a time.
Note 4: Capacitance is guaranteed by periodic testing.
Note 5: CPD determines the no load AC power consumption of any CMOS device. For complete explanation, see 54C and 74C Family Characteristics application

8 times faster than 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 TRI-STATE bus is redistributed by the
CD4514B 4-bit latch/decoder. Using the 4-bit address,
INA – IND, the information on the inhibit line can be transferred to the addressed output line to the desired output
registers, A – 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 CD4512 8-channel data selectors are used here with
the CD4514B 4-bit latch/decoder to effect a complex data
routing system. A total of 16 inputs from data registers are
selected and transferred via a TRI-STATEÉ 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 8 inputs on
both CD4512 data selectors. One register is assigned to
each input. The signals on A0, A1 and A2 choose 1-of-8
inputs for transfer out to the TRI-STATE data bus. A fourth
signal, labelled Dis, disables one of the CD4512 selectors,
assuring transfer of data from only one register.
In addition to a choice of input registers, 1–16, the rate of
transfer of the sequential information can also be varied.
That is, if the CD4512 were addressed at a rate that is
