75492 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 50 m A source or sink capability per driver (DS75491) Y 250 m A sink capability per driver (DS75492) Y MOS patability (low input current) Y Low standby power Y High-gain Darlington circuits Schematic and Connection Diagrams DS75491 (each driver) DS75492 (each driver) TL F 5830 - 1 DS75491 Dual-In-Line Package TL F 5830 - 2 DS75492 Dual-In-Line Package Top View TL F 5830 - 3 Top View Order Number DS75491N DS75492M or DS75492N See NS Package Number M14A or N14A TL F 5830 - 4 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 Input Voltage Range (Note 4) b5V to VSS Collector Output Voltage (Note 5) 10V 10V Collector Output to Input Voltage 10V 10V Emitter to Ground Voltage (VI t 5V) Emitter to Input Voltage 10V 5V Voltage at VSS Terminal with Respect to any Other Device Terminal 10V 10V Collector Output Current Each Collector Output All Collector Outputs 50 m A 250 m A 200 m A 600 m A Continuous Total Dissipation DS75491 600 m...
