Description

The CDB402E is a TTL digital integrated circuit of the CDB series of IPRS Băneasa: quadruple 2-input NOR gates [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the CDB402E and CDB402EM together with the 54LS02 (marked as preliminary data) and the 74LS02, as quadruple 2-input NOR gates in a TO-116 package, with the logic function Y = ¬(A+B) [1]. By the catalog’s table of families, the CDB402E and 74LS02 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB402EM and 54LS02 at −55…+125 °C from 4.50…5.50 V [2].
