1 Features

• Adds two binary numbers

• Full internal lookahead

• Fast ripple carry for economical expansion

• Operates with both positive and negative logic

• Fanout (over temperature range)

– Standard outputs 10 LSTTL loads

– Bus driver outputs 15 LSTTL loads

• Wide operating temperature range: –55℃ to 125℃

• Balanced propagation delay and transition times

• Significant power reduction compared to LSTTL

Logic ICs

• HC types

– 2 V to 6 V operation

– High noise immunity: NIL = 30%, NIH = 30% of

VCC at VCC = 5 V

• HCT types

– 4.5 V to 5.5 V operation

– Direct LSTTL input logic compatibility,

VIL = 0.8 V (max), VIH = 2 V (min)

– CMOS input compatibility, II ≤ 1 μA at VOL, VOH

2 Description

The CDx4HC283 and CDx4HCT283 contain 4-bit

binary adders. The HCT device has TTL-voltage

compatible inputs.
