SN74LS283

4-BIT BINARY FULL ADDER WITH FAST CARRY;

The SN54 /74LS283 is a high-speed 4-Bit Binary Full Adder with internal carry lookahead. It accepts two 4-bit binary words (A1–A4, B1–B4) and a Carry Input (C0). It generates the binary Sum outputs (∑1–∑4) and the Carry Output (C4) from the most significant bit. The LS283 operates with either active HIGH or active LOW operands (positive or negative logic).

具有快速进位功能的 4 位二进制全加器; • Full-Carry Look-Ahead Across the Four Bits\n• Systems Achieve Partial Look-Ahead Performance with the Economy of Ripple Carry\n• Supply Voltage and Ground on Corner Pins to Simplify P-C Board Layout;

The '283 and 'LS283 adders are electrically and functionally identical to the '83A and 'LS83A, respectively; only the arrangement of the terminals has been changed. The 'S283 high performance versions are also functionally identical. These improved full adders perform the addition of two 4-bit binary words. The sum () outputs are 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, typically, for the '283 and 'LS283, and 7.5 nanoseconds for the 'S283. This capability provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple-carry implementation. The adder logic, including the carry, is implemented in its true form. End around carry can be accomplished without the need for logic or level inversion. Series 54, Series 54LS, and Series 54S circuits are characterized for operation over the full temperature range of -55°C to 125°C.Series 74, Series 74LS, and Series 74S circuits are characterized for 0°C to 70°C operation. \n
