1 / 4 page © 2000 Fairchild Semiconductor Corporation DS006544 www.fairchildsemi.com September 1986 Revised February 2000 DM74145 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 s Full decoding of input logic s 80 mA sink-current capability s All outputs are OFF for invalid BCD input conditions Ordering Code: Connection Diagram Function Table H = HIGH Level (OFF) L = LOW Level (ON) Order Number Package Number Package Description DM74145N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide No. Inputs Outputs DCBA 0123456789 0 LLLLL HHHHHHHHH 1 L L L HH L HHHHHHHH 2 L L H L H H L HHHHHHH 3 L L HHHHH L HHHHHH 4 L H L L HHHH L HHHHH 5 L H L HHHHHH L HHHH 6 L HH L HHHHHH L HHH 7 L HHHHHHHHHH L H H 8 H L L L HHHHHHHH L H 9 H L L HHHHHHHHHH L I H L H L HHHHHHHHHH N H L HHHHHHHHHHHH V H H L L HHHHHHHHHH A H H L HHHHHHHHHHH L HHH L HHHHHHHHHH I HHHHHHHHHHHHHH D |
