Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The A6278 and A6279 devices are specifically designed for LED display
applications. Each of these BiCMOS devices includes a CMOS shift register,
accompanying data latches, and NPN constant-current sink drivers. The A6278
contains 8 sink drivers, while there are 16 in the A6279.
The CMOS shift register and latches allow direct interfacing with
microprocessor-based systems. With a 3.3 or 5 V logic supply, typical serial
data-input rates can reach up to 25 MHz. The LED drive current is determined
by the user’s selection of a single resistor. A CMOS serial data output
permits cascading between multiple devices in applications requiring
additional drive lines. Open LED connections can be detected and signaled back
to the host microprocessor through the SERIAL DATA OUT pin.
Features and Benefits
▪ 3.0 to 5.5 V logic supply range
▪ Schmitt trigger inputs for improved noise immunity
▪ Power-On Reset (POR)
▪ Up to 90 mA constant-current sinking outputs
▪ LED open circuit detection
▪ Low-power CMOS logic and latches
▪ High data input rate
▪ 20 ns typical staggering delay on the outputs
▪ Internal UVLO and thermal shutdown (TSD) circuitry
