Product Summary

The SN74HC283DR is a 4-bit binary full adder with fast carry. The sum outputs are provided for each bit, and the resultant carry (C4) is obtained from the fourth bit. The SN74HC283DR features full internal look-ahead across all four bits generating the carry term. This capability provides the system designer with partial look-ahead performance at the economy and reduced package count of a ripple carry implementation.

Parametrics

SN74HC283DR absolute maximum ratings: (1)Supply voltage range: -0.5V to 7V; (2)Input clamp current, IIK(VI＜0 or VI ＞VCC):±20mA; (3)Output clamp current, IOK(VO＜0 or VO ＞VCC): ±20mA;(4)Continuous output current, IO (IO=0 to VCC): ±25 mA; (5)Continuous current through VCC or GND pins: ±50 mA; (6)Lead temperature 1.6mm (1/16 in) from case for 10s: D or N package: 260℃; (7)Storage temperature range: -65℃ to 150℃.

Features

SN74HC283DR features: (1)Full-Carry Look-Ahead across the four bits; (2)Systems achieve partial look-ahead performance with the economy of ripple carry; (3)Supply voltage and ground on corner pins to simplify P-C board layout; (4)Package options include plastic "small outline" packages, ceramic chip carries, and standard plastic and ceramic 300-mil DIPs; (5)Dependable Texas instruments Quality and reliability.
