DM5445 DM7445 BCD to Decimal Decoders Drivers June 1989 DM5445 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 compatible for interfacing with most MOS integrated circuits Features Y Full decoding of input logic Y 80 mA sink-current capability Y All outputs are off for invalid BCD input conditions Connection Diagram Function Table Dual-In-Line Package TL F 6517 – 1 Order Number DM5445J DM5445W or DM7445N See NS Package Number J16A N16E or W16A Inputs No Outputs DCBA0 1 2 3 4 5 6 7 8 9 0 L L L L LHHHHHHHHH 1 L L LHHLHHHHHHHH 2 L LHLHHLHHHHHHH 3 L LHHHHHLHHHHHH 4 LHL LHHHHLHHHHH 5 LHLHHHHHHLHHHH 6 LHHLHHHHHHLHHH 7 LHHHHHHHHHHLHH 8 HL L LHHHHHHHHLH 9 HL LHHHHHHHHHHL I HLHLHHHHHHHHHH N HLHHHHHHHHHHHH V HHL LHHHHHHHHHH A HHLHHHHHHHHHHH L HHHLHHHHHHHHHH I HHHHHHHHHHHHHH D H e High Level (Off) L e Low Level (On) C1995 National Semiconductor Corporation TL F 6517 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note) If Military Aerospace specified dev...
