Description
The CDB450E is a TTL logic integrated circuit, a dual expandable 2 × 2-input AND-OR-INVERT 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 |
| 450 | 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 CDB450E and CDB450EM as dual 2-wide 2-input AND-OR-INVERT gates (one gate expandable) in a TO-116 package, with the logic function Y = ¬(A·B + C·D + X), where X is the output of the CDB460EM/E expander [3]. By the catalog’s table of families, the CDB450E works at 0…+70 °C from a 4.75…5.25 V supply, and the CDB450EM at −55…+125 °C from 4.50…5.50 V [4].
