74LS283 4-Bit Binary Full Adder IC With Fast Carry | Datasheet

The 74LS283 4-Bit Binary full adders perform the addition of two 4-bit binary words. The sum of the outputs is provided for each bit and the resultant carry (C4) is obtained from the fourth bit. These adders feature full internal look-ahead across all four bits generating the carry term in ten nanoseconds. The 74LS283 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL components. The IC 74LS283 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.

What is a Binary Full Adder Circuit?

A Binary full adder circuit is a digital circuit that performs addition. Full adders are implemented with logic gates in hardware. A full adder adds three one-bit binary numbers, two operands, and a carry bit. The adder outputs two numbers, a sum and a carry bit.
