Not to scale

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 constantcurrent 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 selection of a single resistor. A CMOS serial data output permits cascaded 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 A6275.

Three package styles are provided through-hole DIP suffix A , surface-mount SOIC suffix LW , and TSSOP with exposed thermal pad suffix LP . In normal applications, the copper leadframe and low logic-power dissipation of the DIP allow it to sink maximum rated current through all outputs continuously over the operating temperature range 90 mA, V drop, 85°C . All packages are lead Pb free, with 100% matte tin leadframe plating.
