74HC283 ( 4 Bit Binary Adder) 7483 Open Collector Outputs Require Pull-Up

Open Collector Outputs Require Pull-Up Resistors

Single-Supply Operation : 2

Voice commands are stored in one large group like a library

one for primary and another for backup

all the segment outputs are HIGH independent of all other input conditions

74HC283 ( 4 Bit Binary Adder) 7483 Open Collector Outputs Require Pull-UpIntroduction : 74HC283 is a full adder performs the addition of two 4 bit binary numbers utilizing advanced silicon gate CMOS technology. The sum (R) outputs are provided for each bit and the resultantcarry (C4) is obtained from the fourth bit. These adders feature full internal look ahead across all four bits. This provides the system designer with partial look ahead performance at the economy and reduced package count of a ripple carry
