DESCRIPTION

· The ′F283 is a 4-bit full adder performing binary addition with sum and carry outputs.

· It features full internal look-ahead across all four bits, generating the carry term C4 in typically 5.7 ns.

· The device supports both positive and negative logic operands.

· It is available in various package options including plastic small-outline, ceramic chip carriers, and standard plastic and ceramic 300-mil DIPs.

FEATURES

· Full-carry look-ahead across four bits.

· Achieves partial look-ahead performance with the economy of ripple-carry.

· End-around carry capability without the need for logic or level inversion.

· Operates over a wide temperature range: -55°C to 125°C for SN54F283 and 0°C to 70°C for SN74F283.

APPLICATIONS

· Suitable for systems requiring high-speed binary addition.

· Ideal for applications needing partial look-ahead performance with reduced package count.

· Can be used in both military and commercial temperature range environments.
