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

(10–15) binary input conditions. These decoders feature

high-performance, NPN output transistors designed for use

as indicator/relay drivers, or as open-collector logic-circuit

drivers. The high-breakdown output transistors are com-

patible for interfacing with most MOS integrated circuits.

Features
