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 ap-
plications. 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 bright-
ness control. Expansion beyond four digits is possible with a
cascade connection to a second device. The device automati-
cally refreshes and maintains the displayed information.
