Description

The CDB411HE is a triple 3-input AND gate, a logic integrated circuit listed in the Agenda radioelectronistului (1st edition, 1983) among the logic integrated circuits made by IPRS Băneasa [1]. Its codes (CDB411HE and CDB411HEM) are in the Variants table.

It appears only in the 1st edition of the Agenda, printed „CDB 411 HE; CDB 411 HEM”; the 2nd edition (1989) no longer lists it [1].

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

Part Meaning
CDB characteristic prefix of IPRS Băneasa for logic integrated circuits
411 serial number of the circuit (2–4 digits)
–, H series type: – = standard (medium speed), H = fast
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 CDB411HE and CDB411HEM together with the 54LS11 (marked as preliminary data) and the 74LS11, as triple 3-input AND gates in a TO-116 package, with the logic function Y = A·B·C [3]. By the catalog’s table of families, the CDB411HE and 74LS11 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB411HEM and 54LS11 at −55…+125 °C from 4.50…5.50 V [4].
