Description

The CDB4157 is a quad 2-to-1 multiplexer, a logic integrated circuit listed in the Agenda radioelectronistului (1st edition, 1983) among the logic integrated circuits made by IPRS Băneasa [1].

It appears only in the 1st edition of the Agenda, printed „CDB 4157”; 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
4157	serial number of the circuit (2–4 digits)

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 CDB4157E and CDB4157EM together with the 54LS157 and 74LS157 (both marked as preliminary data), as quad 2-to-1 line data selectors/multiplexers (noninverted data outputs) in an MP-117 package [3]. By the catalog’s table of families, the CDB4157E and 74LS157 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB4157EM and 54LS157 at −55…+125 °C from 4.50…5.50 V [4].
