4-Bit Binary Full Adder
The TC74HC283A is a high speed CMOS 4-BIT BINARY FULL
ADDER fabricated with silicon gate C²MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
Sum (Σ) outputs are provided for each bit and a resultant carry
(C4) is obtained from the fourth bit.
This adder features full internal look-ahead across all four bits.
A4 × n bit binary adder is easily built up by cascading the
HC283A without any additional logic.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: t_pd = 17 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |I_OH| = I_OL = 4 mA (min)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_CC (opr) = 2 to 6 V
• Pin and function compatible with 74LS283
