Fairchild Semiconductor DM74145

The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. These decoders feature high-performance, NPN output transistors designed for use as indicator/relay drivers, or as open-collector logic-circuit drivers.

GENERAL DESCRIPTION

These BCD-to-decimal decoders/drivers consist of eight inverters and ten, four-input NAND gates. Full decoding of BCD input logic ensures that all outputs remain OFF for all invalid (10–15) binary input conditions. The high-breakdown output transistors are compatible for interfacing with most MOS integrated circuits.

FEATURES

s Full decoding of input logic s 80 mA sink-current capability s All outputs are OFF for invalid BCD input conditions Ordering Code: Order Number DM74145N Package Number N16E Package
