The DM74LS283N from ON Semiconductor is a 4-bit binary adder designed for performing addition of two 4-bit binary numbers. It features full internal look-ahead across all four bits, providing partial look-ahead performance with the economy of ripple-carry implementation. The device outputs the sum for each bit and the resultant carry from the fourth bit.
Key electrical specifications include a supply voltage range of 4.75V to 5.25V. Typical add times are 25 ns for two 8-bit words and 45 ns for two 16-bit words. Typical power dissipation is 95 mW per 4-bit adder.
This component is housed in a 16-lead PDIP package with a 0.300-inch width, suitable for through-hole mounting. The operating temperature range is 0°C to 70°C.
The adder logic is implemented in its true form, allowing for end-around carry without logic or level inversion. This makes it suitable for systems requiring efficient binary addition.
