Description
The ’HC283 and ’HCT283 binary full adders add two 4-bit
binary numbers and generate a carry-out bit if the sum
exceeds 15.
Because of the symmetry of the add function, this device
can be used with either all active-high operands (positive
logic) or with all active-low operands (negative logic). When
using positive logic the carry-in input must be tied low if there
is no carry-in.

• Significant Power Reduction Compared to LSTTL
Logic ICs
• HC Types
- 2V to 6V Operation
- High Noise Immunity: N_IL = 30%, N_IH = 30% of V_CC
at V_CC = 5V
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
V_IL= 0.8V (Max), V_IH = 2V (Min)
- CMOS Input Compatibility, I_l ≤ 1µA at V_OL, V_OH
