DABiC-IV 32-Bit Serial Input
Latched Source Driver
Description (continued)
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-) applications. 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.
