Product Information

Data Sheet 26182.124D* 6810 DABiC-IV, 10-BIT SERIAL-INPUT, LATCHED SOURCE DRIVER A6810xA The A6810– devices combine 10-bit CMOS shift registers, accompanying data latches and control circuitry with bipolar sourcing outputs and pnp active pull downs. Designed primarily to drive vacuumfluorescent displays, the 60 V and -40 mA output ratings also allow these devices to be used in many other peripheral power driver applications. The A6810– feature an increased data input rate (compared with the older UCN/UCQ5810-F) and a controlled output slew rate. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 3.3 V or 5 V logic supply, serial-data input rates of at least 10 MHz . A CMOS serial data output permits cascade connections in applications requiring additional drive lines. Similar devices are available as the A6812– (20 bits) and A6818– (32 bits). 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/or microprocessors and to meet government emissions regulations. For inter-digit blanking, all output drivers can be disabled and all sink drivers turned on with a BLANKING input high. The pnp active pull-downs will sink at least 2.5 mA. The A6810– are available in two temperature ranges for optimum performance in commercial (suffix S-) or industrial (suffix E-) applications. They are provided in two package styles for through-hole DIP (suffix -A) or minimum-area surface-mount SOIC (suffix -LW). Copper lead frames, low logic-power dissipation, and low outputsaturation voltages allow all devices to source 25 mA from all outputs continuously over the maximum operating temperature range.
