TB62710P

TB62710P/F/FN TOAHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62710P, TB62710F, TB62710FN 8-Bit Constant-Current LED Driver for Cathode Common LED The TB62710P, TB62710F and TB62710FN are specifically designed for use as LED and LED display (cathode-common) Constant-current drivers. The constant-current output circuits can be set up using an external resistor (IOUT = −90 mA max). These ICs are monolithic integrated circuits have been designed using the Bi-CMOS process. The devices consist of an 8-bit shift register, a latch, an ANDgate and constant-current drivers. FEATURES · Constant-current output: A single resistor can be used to set any output current in the range −5~−90 mA. · Maximum clock frequency: fCLK = 15 MHz (operating while connected in cascade, Topr = 25°C) · 5-V CMOS compatible input · Packages: P-type: DIP20-P-300-2.54A F-type: SSOP24-P-300-1.00 FN-type: SSOP20-P-225-0.65A · Constant-output-current accuracy: Output − GND Voltage Current accuracy between bits between ICs Output Current (max) ≥ 2.0 V (min) ≥ 1.5 V (min) ±6% ±15% −5~−90 mA −5~−40 mA TB62710P TB62710F TB62710FN Weight DIP20-P-300-2.54A: 2.25 g (Typ.)
