TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

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: tpd = 17 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 µA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Pin and function compatible with 74LS283
Pin Assignment
Note: xxxFN (JEDEC SOP) is not available in
Japan.
