A6833 DABiC-5 32-Bit Serial Input Latched Sink Drivers Last Time Buy This part is in production but has been determined to be LAST TIME BUY. This classification indicates that the product is obsolete and notice has been given. Sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because of obsolescence in the near future. Samples are no longer available. Date of status change November 1, 2010 Deadline for receipt of LAST TIME BUY orders April 30, 2011 Recommended Substitutions: For existing customer transition, and for new customers or new applications, contact Allegro Sales.

These devices can also be used to drive multiplexed LED displays or incandescent lamps within their 125 mA peak output current rating. The combination of bipolar and MOS technologies gives the A6833 smart power IC an interface flexibility beyond the reach of standard buffers and power driver circuits. This 32-bit drivers have bipolar open-collector NPN Darlington outputs, a CMOS data latch for each of the drivers, a 32-bit CMOS shift register, and CMOS control circuitry. The high-speed CMOS shift registers and latches allow operation with most microprocessor-based systems. Use of these drivers with TTL may require input pull-up resistors to ensure an input logic high. CMOS serial data outputs permit cascading for applications requiring additional drive lines. The A6833 is supplied in a 44-lead plastic chip carrier quad pack , intended for surface mounting on solder lands with in. mm centers. These devices are lead Pb free, with 100% matte tin plated leadframes.
