PP-015-3 ABSOLUTE MAXIMUM RATINGS at +25°C Free-Air Temperature 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 pulldown 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 appropriate 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.

No. A-14,357 Information present at an input is transferred to its latch when the STROBE and ENABLE are high. The latches will continue to accept new data as long as both STROBE and ENABLE are held high. With either STROBE or ENABLE in the low state, no information can be loaded into the latches. A.

Higher speeds may be attainable with increased supply voltage; operation at high temperatures will reduce the specified maximum clock frequency. When the BLANKING input is high, all of the output buffers are disabled (off) without affecting the information stored in the latches. With the BLANKING input low, the outputs are controlled by the state of the latches.
