displays, the UCN5815A and UCN5815EP BiMOS II integrated
circuits consist of eight npn Darlington source drivers with output pull-
down resistors, a CMOS latch for each driver, and common STROBE,
BLANKING, and ENABLE functions.
the original BiMOS circuits. With a 5 V logic supply, they will operate
to at least 4.4 MHz. With a 12 V supply, significantly higher speeds
are obtained. The CMOS inputs cause minimum loading and are
compatible with standard CMOS and NMOS logic commonly found in
microprocessor designs. TTL circuits may require the use of appropri-
ate pull-up resistors.
digit drivers in vacuum-fluorescent displays. All eight outputs can be
activated simultaneously at ambient temperatures in excess of 75°C.
To simplify printed wiring board layout, output connections are
opposite the inputs. A minimum component display subsystem,
requiring few or no discrete components, can be assembled using the
UCN5815A/EP with the UCN5810AF/EPF/LWF, UCN5812AF/EPF,
or UCN5818AF/EPF serial-to-parallel latched drivers.
