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– features an increased data input rate
(compared with the older UCN/UCQ5818–F) 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–
(10 bits) and A6812– (20 bits).
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.
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.
