The A6275EA and A6275ELW are specifically designed for LEDdisplay applications. Each BiCMOS device includes an 8-bit CMOS shift register, accompanying data latches, and eight npn constantcurrent sink drivers. Except for package style and allowable package power dissipation, the two devices are identical. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 5 V logic supply, typical serial data-input rates are up to 20 MHz.
