High-Speed
CMOS Logic 4-Bit Binary Full Adder with Fast Carry
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.
