Features, Applications

The A6276EA and A6276ELW are specifically designed for LEDdisplay 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 two devices are identical. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With 5 V logic supply, typical serial data-input rates are 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. Two package styles are provided for through-hole DIP (suffix A) or surface-mount SOIC (suffix LW). Under normal applications, a copper lead frame and low logic-power dissipation allow the dual in-line package to sink maximum rated current through all outputs continuously over the operating temperature range (90 mA, 0.75 V drop, +85C). Both devices are also available for operation over the standard temperature range +85C. To order, change the suffix letter `E' to `S'.

Note that the A6276EA (DIP) and the A6276ELW (SOIC) are electrically identical and share a common terminal number assignment.

Caution: These CMOS devices have input static protection (Class 2) but are still susceptible to damage if exposed to extremely high static electrical charges.
