Description

The CDB432E is a TTL digital integrated circuit of the CDB series of IPRS Băneasa: quadruple 2-input OR gates [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the CDB432E and CDB432EM together with the 54LS32 (marked as preliminary data) and the 74LS32, as quadruple 2-input OR gates in a TO-116 package, with the logic function Y = A+B [1]. By the catalog’s table of families, the CDB432E and 74LS32 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB432EM and 54LS32 at −55…+125 °C from 4.50…5.50 V [2].
