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 A6818鈥?features an increased data input rate
(compared with the older UCN/UCQ5818鈥揊) and a controlled output slew rate.
processor-based systems. With a 3.3 V or 5 V logic supply, typical serial-data
input rates are up to 33 MHz.
requiring additional drive lines. Similar devices are available as the A6810鈥?/div>
(10 bits) and A6812鈥?(20 bits).
The A6818鈥?output source drivers are npn Darlingtons, capable of
sourcing up to 40 mA. The controlled output slew rate reduces electromag-
netic noise, which is an important consideration in systems that include
telecommunications and/or microprocessors and to meet government emis-
sions 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 (E-), and extended industrial (K-) applica-
tions. The package style provided is the minimum-area surface-mount PLCC
(suffix -EP). Copper lead frames, low logic-power dissipation, and low
output-saturation voltages allow these devices to drive most multiplexed
vacuum-fluorescent displays over the maximum operating temperature range.
The lead (Pb) free versions have 100% matte tin leadframe plating.
