Description

The CDB483E is a TTL logic integrated circuit, a 4-bit binary adder, listed in the Agenda radioelectronistului (2nd edition, 1989) among the integrated circuits made in Romania by IPRS Băneasa, in an MP-117 package [1]. Its pinout is in the Gallery.

The 1st edition of the Agenda (1983) lists no CDB 483 E, but a CDB484E, „Sumator complet de 4 biți” (4-bit full adder) [3].

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

Part Meaning
CDB characteristic prefix of IPRS Băneasa for logic integrated circuits
483 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].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the CDB483E and CDB483EM as 4-bit binary full adders with fast carry in an MP-117 package [4]. By the catalog’s table of families, the CDB483E works at 0…+70 °C from a 4.75…5.25 V supply, and the CDB483EM at −55…+125 °C from 4.50…5.50 V [5].
