Description

The CDB4123E is a TTL digital integrated circuit of the CDB series of IPRS Băneasa: dual retriggerable monostable multivibrators with clear [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the CDB4123E and CDB4123EM together with the 54LS123 and 74LS123 (both marked as preliminary data), as dual retriggerable monostable multivibrators with clear in an MP-117 package [1]. By the catalog’s table of families, the CDB4123E and 74LS123 work at 0…+70 °C from a 4.75…5.25 V supply, and the CDB4123EM and 54LS123 at −55…+125 °C from 4.50…5.50 V [2].
