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 typically

operate above 5 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

appropriate 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 oppo-

site 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.
