74HC283  
4-bit binary full adder with fast carry  
Rev. 03 — 11 November 2004  
Product data sheet  
1. 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.  
2. Features  
High-speed 4-bit binary addition  
Cascadable in 4-bit increments  
Fast internal look-ahead carry  
Low-power dissipation  
Complies with JEDEC standard no. 7A  
ESD protection:  
HBM EIA/JESD22-A114-B exceeds 2000 V  
MM EIA/JESD22-A115-A exceeds 200 V.  
Multiple package options  
Specified from 40 °C to +80 °C and from 40 °C to +125 °C.
