DM5445DM7445 BCD to Decimal DecodersDrivers

General Description

These BCD-to-decimal decodersdrivers consist of eight in-

verters 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 indicatorrelay drivers or as open-collector logic-circuit

drivers The high-breakdown output transistors are compati-

ble for interfacing with most MOS integrated circuits

Features
