The A6812 devices combine a 20-bit CMOS shift register, accompanying data latches and control circuitry with bipolar sourcing outputs and pnp active pull downs. Designed primarily to drive vacuum-fluorescent displays, the 60 V and -40 mA output ratings also allow these devices to be used in many other peripheral power driver applications. The A6812 features an increased data input rate (compared with the older UCN/UCQ5812-F) and a controlled output slew rate. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With 5 V logic supply, they will operate to at least 10 MHz. A CMOS serial data output permits cascade connections in applications requiring additional drive lines. Similar devices are available as the A6809 and A6810 (10 bits), A6811 (12 bits), and A6818 (32 bits). The A6812 output source drivers are npn Darlingtons, capable of sourcing 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. Three temperature ranges are available for optimum performance in commercial (suffix S-), industrial (suffix E-), or automotive (suffix K-) applications. Package styles are provided for through-hole DIP (suffix -A), surface-mount SOIC (suffix -LW), or minimum-area surface-mount PLCC (suffix -EP). Copper lead frames, low logicpower dissipation, and low output-saturation voltages allow these drivers to source 25 mA from all outputs continuously to more than +43°C (suffix -LW), +61°C (suffix -EP), or +77°C (suffix -A).
