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).
