Description

The CDB484E is a 4-bit full adder, a logic integrated circuit listed in the Agenda radioelectronistului (1st edition, 1983) among the logic integrated circuits made by IPRS Băneasa [1].

It appears only in the 1st edition of the Agenda, printed „CDB 484 E”; the 2nd edition (1989) no longer lists it [1].

The 2nd edition (1989) lists instead the CDB483E, a 4-bit binary adder, and no CDB 484 E [3].

Coded as (IPRS Băneasa code for logic integrated circuits) [2]:

Part Meaning
CDB characteristic prefix of IPRS Băneasa for logic integrated circuits
484 serial number of the circuit (2–4 digits)
E package: E = dual-in-line (plastic DIL)

The logic integrated circuits of IPRS Băneasa (generally TTL) are always made in the E version (TO-116 package), some also in the P version (TO-85 package) [2].
