Description
The CDB409E is a TTL logic integrated circuit, a quad 2-input AND gate with open-collector outputs (5.5 V), 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 codes (CDB409E and CDB409EM) are in the Variants table; the pinout is in the Gallery.
The 1st edition of the Agenda (1983) gives the open-collector outputs as 30 V (the 2nd edition: 5.5 V) [3].
Coded as (IPRS Băneasa code for logic integrated circuits) [2]:
| Part | Meaning |
|---|---|
| CDB | characteristic prefix of IPRS Băneasa for logic integrated circuits |
| 409 | serial number of the circuit (2–4 digits) |
| E | package: E = dual-in-line (plastic DIL) |
| –, M | operating temperature range: – = 0…+70 °C, M = −55…+125 °C |
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 CDB409E and CDB409EM together with the 54LS09 (marked as preliminary data) and the 74LS09, as quadruple 2-input AND gates with open-collector outputs in a TO-116 package, with the logic function Y = A·B [4]. By the catalog’s table of families, the CDB409E and 74LS09 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB409EM and 54LS09 at −55…+125 °C from 4.50…5.50 V [5].
