Description

The CDB486E is a TTL logic integrated circuit, a quad 2-input exclusive-OR gate, listed in the Agenda radioelectronistului (2nd edition, 1989) among the integrated circuits made in Romania by IPRS Băneasa, in a TO-116 package [1]. Its pinout is in the Gallery.

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

Part Meaning
CDB characteristic prefix of IPRS Băneasa for logic integrated circuits
486 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 CDB486E and CDB486EM together with the 54LS86 and 74LS86 (both marked as preliminary data), as quadruple 2-input exclusive-OR gates in a TO-116 package, with the logic function Y = A ⊕ B = A·¬B + ¬A·B [3]. By the catalog’s table of families, the CDB486E and 74LS86 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB486EM and 54LS86 at −55…+125 °C from 4.50…5.50 V [4].
