General description
The 74HC283 is a high-speed Si-gate CMOS device and is pin compatible with low power
Schottky TTL (LSTTL). The 74HC283 is specified in compliance with JEDEC
standard no. 7A.
The 74HC283 adds two 4-bit binary words (An plus Bn) plus the incoming carry (CIN).
The binary sum appears on the sum outputs (S1 to S4) and the out-going carry (COUT)
according to the equation:
CIN + (A1 + B1) + 2(A2 + B2) + 4(A3 + B3) + 8(A4 + B4) =
= S1 + 2S2 + 4S3 + 8S4 + 16COUT
Where (+) = plus.
Due to the symmetry of the binary add function, the 74HC283 can be used with either all
active HIGH operands (positive logic) or all active LOW operands (negative logic). In case
of all active LOW operands the results S1 to S4 and COUT should be interpreted also as
active LOW. With active HIGH inputs, CIN must be held LOW when no carry in is
intended. Interchanging inputs of equal weight does not affect the operation, thus CIN, A1,
B1 can be assigned arbitrarily to pins 5, 6, 7, etc.
See the 74HC583 for the BCD version.

74HC283
4-bit binary full adder with fast carry
12. Waveforms
13. Application information
Figure 8
shows a 3-bit adder using the 74HC283. Trying the operand inputs of the fourth
adder (A4 and B4) LOW makes S4 dependent on, and equal to, the carry from the third
adder.
Figure 9
, based on the same principle, shows a method of dividing the 74HC283 into a
2-bit and 1-bit adder. The third stage adder (A3, B3 and S3) is used simply as means of
transferring the carry into the fourth stage (via A3 and B3) and transferring the carry from
V
M
= 0.5

I
.

4-bit binary full adder with fast carry
the second stage on S3. As long as A3 and B3 are the same, HIGH or LOW, they do not
influence S3. Similarly, when A3 and B3 are the same, the carry into the third stage does
not influence the carry out of the third stage.
Figure 10
shows a method of implementing a 5-input encoder, where the inputs are
equally weighted. The outputs S1, S2 and S3 produce a binary number equal to the
number inputs (I1 to I5) that are HIGH.
Figure 11
shows a method of implementing a 5-input majority gate. When three or more
inputs (I1 to I5) are HIGH, the output M5 is HIGH.

[1]
Please consult the most recently issued data sheet before initiating or completing a design.
[2]
The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at
URL http://www.semiconductors.philips.com.
[3]
For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
17. Definitions
Short-form specification -- The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition -- Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
Application information -- Applications that are described herein for any
of these products are for illustrative purposes only. Philips Semiconductors
make no representation or warranty that such applications will be suitable for
the specified use without further testing or modification.
18. Disclaimers
Life support -- These products are not designed for use in life support
appliances, devices, or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors
customers using or selling these products for use in such applications do so
at their own risk and agree to fully indemnify Philips Semiconductors for any
damages resulting from such application.
Right to make changes -- Philips Semiconductors reserves the right to
make changes in the products - including circuits, standard cells, and/or
software - described or contained herein in order to improve design and/or
performance. When the product is in full production (status `Production'),
relevant changes will be communicated via a Customer Product/Process
Change Notification (CPCN). Philips Semiconductors assumes no
