A6832 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 This classification indicates that the product is obsolete and notice has been given.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. NOTE For detailed information on purchasing options, contact your local Allegro field applications engineer or sales representative. A6832 DABiC-5 32-Bit Serial Input Latched Sink Drivers to 5 V logic supply range To 10 MHz data input rate Schmitt trigger inputs for improved noise immunity Low-power CMOS logic and latches 40 V current sink outputs Low saturation voltage operation available Applications: Thermal printheads Multiplexed LED displays Incandescent lamps Package 44-pin PLCC suffix EP Not to scale Intended originally to drive thermal printheads, the A6832 has been optimized for low output-saturation voltage, high-speed operation, and pin configurations that are the most convenient for the tight space requirements of high-resolution printheads. These integrated circuits can also be used to drive multiplexed LED displays or incandescent lamps at up to 125 mA peak current. The combination of bipolar and MOS technologies gives the A6832 arrays an interface flexibility beyond the reach of standard buffers and power driver circuits. The devices each have 32 bipolar NPN open-collector saturated drivers, a CMOS data latch for each of the drivers, two 16-bit CMOS shift registers, and CMOS control circuitry. The highspeed 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. MOS serial data outputs permit cascading for interface applications requiring additional drive lines. The A6832 is supplied in a 44-lead plastic leaded chip carrier, for surface-mount applications requiring minimum area. These devices are lead Pb free, with 100% matte tin plated leadframes.
