16-BIT SERIAL-INPUT, CONSTANTCURRENT LATCHED LED DRIVER
The A6276 is specifically designed for LED-display applications. Each BiCMOS device includes a 16-bit CMOS shift register, accompanying data latches, and 16 npn constant-current sink drivers. Except for package style and allowable package power dissipation, the device options 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. The LED drive current is determined by the user’s selection of a single resistor. A CMOS serial data output permits cascade connections in applications requiring additional drive lines. For inter-digit blanking, all output drivers can be disabled with an ENABLE input high. Similar 8-bit devices are available as the A6275EA and A6275ELW. Three package styles are provided: through-hole DIP (suffix A), surface-mount SOIC (suffix LW) and TSSOP with exposed thermal pad (suffix LP). Under normal applications, a copper lead frame and low logic-power dissipation allow the dual in-line package to sink maximum rated current through al……
