DS75491 Datasheet | National Semiconductor

Description The DS75491 and DS75492 are interface circuits designed to be used in conjunction with MOS integrated circuits and mon-cathode LEDs in serially addressed multi-digit displays The number of drivers required for this time-multiplexed system is minimized as a result of the segment-address-and-digit-scan method of LED drive Features Y Y Y Y Y 50 m A source or sink capability per driver (DS75491) 250 m A sink capability per driver (DS75492) MOS patability (low input current) Low standby power High-gain Darlington circuits Schematic and Connection Diagrams DS75491 (each driver) DS75492 (each driver) TL F 5830 - 1 TL F 5830 - 2 DS75491 Dual-In-Line Package DS75492 Dual-In-Line Package TL F 5830 - 3 TL F 5830 - 4 Top View Order Number DS75491N DS75492M or DS75492N See NS Package Number M14A or N14A Top View C1995 National Semiconductor Corporation TL F 5830 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications DS75491 DS75492 b 5V to VSS Input Voltage Range (Note 4) Collector Output Voltage (Note 5) 10V 10V Collector Output to Input Voltage 10V 10V Emitter to Ground Voltage (VI t 5V) 10V Emitter to Input Voltage 5V Voltage at VSS Terminal with Respect to any Other Device Terminal 10V 10V Collector Output Current Each Collector Output 50 m A 250 m A All Collector Outputs 200 m A 600 m A Continuous Total Dissipation Operating Temperature Range Storage Temperature Range Lead Temp (Soldering 10 sec) Maximum Power Dissipation at 25 C Molded Package DS75491 600 m W DS75492 600 m W 0 C to a 70 C b 65 C to a 150 C 300 C 300 C 1207 m W 1280 m W Derate molded package 9 66 m W C above 25 C Derate molded package 10 24 m W C above 25 C Electrical Characteristics VSS e 10V (Notes 2 and 3) Symbol DS75491 VCE ON ‘‘ON’’ State Collector Emitter Voltage Input e 8 5V through 1 k X VE e 5V IC e 50 m A VC e 10V...
