SCHS176E – NOVEMBER 1997 – REVISED JULY 2022
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
– 4.5 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.
