Description

The CDB438E is a TTL digital integrated circuit of the CDB series of IPRS Băneasa: quadruple 2-input NAND buffers with open-collector outputs [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the CDB438E and CDB438EM together with the 54LS38 and 74LS38 (both marked as preliminary data), as quadruple 2-input NAND buffers with open-collector outputs in a TO-116 package, with the logic function Y = ¬(A·B) [1]. By the catalog’s table of families, the CDB438E and 74LS38 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB438EM and 54LS38 at −55…+125 °C from 4.50…5.50 V [2].
