Hallo,
brauche einen (pinkompatiblen) Ersatz zum 7445 chip :
"DM7445 BCD to Decimal Decoders/Drivers September 1986 Revised February 2000 DM7445 BCD to Decimal Decoders/Drivers General Description These BCD-to-decimal decoders/drivers consist of eight inverters and ten, four-input NAND gates. The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of BCD input logic ensures that all outputs remain OFF for all invalid (10"
