4-Bit Binary Full Adder
The TC74AC283 is an advanced high speed CMOS 4-BIT
BINARY FULL ADDER fabricated with silicon gate and
double-layer metal wiring C²MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL 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
AC283 without any additional logic.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: t_pd = 7.0 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 8 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Symmetrical output impedance: |I_OH| = I_OL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_CC (opr) = 2~5.5 V
• Pin and function compatible with 74F283
