TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62709N/F Intelligent, Constant Current, 7 segment LED numeric display decoder/driver. For use with common anode configuration numeric displays. The TB62709N/F is an intelligent Constant Current LED display driver designed specifically for seven segment LED display applications. The stand alone device includes all of the decode, multiplex and driver circuitry necessary to control up to four seven segment LED digits. All of the information required to program up to four LED digits is input serially including a 16 step brightness control. Expansion beyond four digits is possible with a cascade connection to a second device. The device automatically refreshes and maintains the displayed information. TB62709N SDIP24-P-300-1.78 Weight: 1.62g (Typ.) TB62709F Features • • • • • • • • Constant Current segment drivers for consistent display brightness. Single device saves labor and board space. Internal character set simplifies design efforts. Automatically handles multiplex and display refresh tasks. 16 step programmable brightness control. Single device controls up to four digits. Available in thru hole and surface mount packages. Data out cascade port for expansion beyond four digits. SSOP24-P-300-1.00 Weight: 0.32g (Typ.)
