Description

The CDB447E is a TTL digital integrated circuit of the CDB series of IPRS Băneasa: BCD-to-seven-segment decoders/drivers with active-low, open-collector, 15 V outputs [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the CDB447E and CDB447EM as BCD-to-seven-segment decoders/drivers with active-low, open-collector, 15 V outputs in an MP-117 package [1]. By the catalog’s table of families, the CDB447E works at 0…+70 °C from a 4.75…5.25 V supply, and the CDB447EM at −55…+125 °C from 4.50…5.50 V [2].
