Description
●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 de ter mined 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.
●Features and Benefits
●▪ Up to 90 mA constant-current outputs
●▪ Undervoltage lockout
●▪ Low-power CMOS logic and latches
●▪ High data input rate
●▪ Functional replacement for TB62706BN/BF
