A6810 10-Bit Serial Input Latched Source Driver Discontinued Product This device is no longer in production. The device should not be purchased for new design applications. Samples are no longer available. Date of status change: November 1, 2010 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. Allegro MicroSystems, Inc. reserves the right to make, from time to time, revisions to the anticipated product life cycle plan for a product to accommodate changes in production capabilities, alternative product availabilities, or market demand. The information included herein is believed to be accurate and reliable. However, Allegro MicroSystems, Inc. assumes no responsibility for its use; nor for any infringements of patents or other rights of third parties which may result from its use. A6810 10-Bit Serial Input Latched Source Driver Features and Benefits Description ▪ Controlled output slew rate ▪ High-speed data storage ▪ 60 V minimum output breakdown ▪ High data-input rate ▪ PNP active pull-downs ▪ Low output-saturation voltages ▪ Low-power CMOS logic and latches ▪ Improved replacements for TL4810x, UCN5810x, and UCQ5810x The A6810 combines 10-bit CMOS shift registers, accompanying data latches, and control circuitry with bipolar sourcing outputs and PNP active pull-downs. Designed primarily to drive vacuum-fluorescent (VF) displays, the 60 V and –40 mA output ratings also allow this device to be used in many other peripheral power driver applications. The A6810 features an increased data input rate (compared with the older UCN/UCQ5810-F) and a controlled output slew rate. Packages: The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 3.3 or 5 V logic supply, serial data-input rates of at least 10 MHz can be attained A CMOS serial data output permits cascaded connections in applications requiring additional drive lines. Similar devices are available as the A6812 (20-bit) and A6818 (32-bit). 18-pin DIP (A package) Not to scale 20-pin SOICW (LW package) The A6810 output source drivers are NPN Darlingtons, capable of sourcing up to 40 mA. The controlled output slew rate reduces electromagnetic noise, which is an important consideration in systems that include telecommunications and microprocessors, and to meet government emissions regulations.

The PNP active pulldowns can sink at least 2.5 mA. The A6810 is available in three temperature ranges for optimum performance in commercial (S), industrial (E), and automotive (K) applications. It is provided in two package styles, through-hole DIP (package A) and surface-mount SOIC (package LW). Copper leadframes, low logic-power dissipation, and low output-saturation voltages allow all devices to source 25 mA from all outputs continuously over the full operating temperature range. The lead (Pb) free versions have 100% matte tin leadframe plating.

This classification indicates that the variant is obsolete and notice has been given. Sale of the variant is currently restricted to existing customer applications. The variant should not be purchased for new design applications because of obsolescence in the near future. Samples are no longer available. Status date change May 3, 2010. Deadline for receipt of LAST TIME BUY orders is October 29, 2010.
