Description

The CDB4151 is an 8-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 4151”; 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
4151 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 CDB4151E and CDB4151EM as 1-of-8 data selectors/multiplexers in an MP-117 package [3]. By the catalog’s table of families, the CDB4151E works at 0…+70 °C from a 4.75…5.25 V supply, and the CDB4151EM at −55…+125 °C from 4.50…5.50 V [4].
