Designed primarily for use with high-voltage vacuum-fluorescent 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.

BiMOS II devices have considerably better data-input rates than 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.

The bipolar outputs may be used as segment, dot (matrix), bar, or 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.

Suffix ‘A’ devices are furnished in a standard 22-pin plastic DIP;suffix ‘EP’ indicates a 28-lead PLCC.

Timing is representative of a 4.4 MHz data input rate. Higher speeds may be

attainable with increased supply voltage; operation at high temperatures will

reduce the specified maximum clock frequency.
