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.

input rates are up to 33 MHz.

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.
