DS8874 Datasheet | National Semiconductor

Description The DS8874 is a 9-digit LED driver which incorporates a shift register input decoding circuit and a low battery indicator Outputs will sink 110 m A at less than 0 5V drop when sequentially selected When the VCC supply falls below 6 5V typical segment current will be furnished at digit 9 time to indicate a low battery condition Pin 13 is generally connected to the decimal point segment on the display so that when a low battery condition exists the left-most decimal point lights up Features 110 m A digit sink Low battery indicator Minimum number of connections MOS patible inputs Connection Diagram Dual-In-Line Package TL F 5843 - 1 Top View Order Number DS8874N See NS Package Number N14A Equivalent Schematic TL F 5843 - 2 C1995 National Semiconductor Corporation TL F 5843 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note 1) Maximum Power Dissipation at 25 C Molded Package Lead Temperature (Soldering 4 sec ) Derate molded package 10 24 m W C above 25 C If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage Input Voltage Output Voltage Storage Temperature Range 10V 3V 10V b 65 C to a 150 C 1280 m W 260 C Operating Conditions Supply Voltage (VCC) Temperature (TA) Min 60 0 Max 95 a 70 Units V C Electrical Characteristics (Notes 2 and 3) Symbol IIH IIL VCCL VCCH IOH VOL Parameter Logical ‘‘1’’ Input Current Logical ‘‘0’’ Input Current Decimal Point ‘‘ON’’ Decimal Point ‘‘OFF’’ Logical ‘‘1’’ Output Current Logical ‘‘0’’ Output Voltage Conditions VCC e Max VIN e 3V VCC e Max VIN e 0 8V Vdp e 2 3V Idp e b4 m A O9 e VOL Vdp e 1V Idp e b10 m A O9 e VOL VCC e Max Output Not Selected VCC e Min Output Selected IO1 e 80 m A VCC e Max Output Selected IO1 e 110 m A ICC Supply Current VCC e Max One Output Selected 0 45 06 13 70 100 1 15 19 Min Typ 0 25 0 05 Max 04 01 60 Units m A m A V V m A V V m A Note 1 ‘‘Absolute Maximum Ratings’’...
