DESCRIPTION

· The ′F283 is a full adder designed for the addition of two 4-bit binary words, providing sum outputs for each bit and a resultant carry output from the fourth bit.

· It features full internal look-ahead across all four bits, generating the carry term C4 in typically 5.7 ns, offering partial look-ahead performance with the economy of ripple-carry.

· The device supports both all-active-high and all-active-low operands and is available in various package options including plastic small-outline packages and ceramic chip carriers.

FEATURES

· Full-carry look-ahead across four bits for enhanced performance.

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

· Package options include plastic small-outline packages, ceramic chip carriers, and standard plastic and ceramic 300-mil DIPs.

· The adder logic, including the carry, is implemented in its true form, allowing end-around carry without the need for logic or level inversion.

APPLICATIONS

· Suitable for systems requiring high-speed arithmetic operations.

· Ideal for applications where economy and reduced package count are crucial.

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