Designed primarily for use with vacuum-fluorescent displays, the UCQ5818AF and UCQ5818EPF smart power BiMOS II drivers combine CMOS shift registers, data latches, and control circuitry, with bipolar highspeed sourcing outputs and DMOS active pull-down circuitry. The highspeed shift register and data latches UCQ5818AF and UCQ5818EPF allow direct interfacing with microprocessor LSI-based systems. A CMOS serial data output enables cascade connections in applications requiring additional drive lines. UCQ5818AF and UCQ5818EPF feature 60 V and -40 mA output ratings, allowing them to be used in many other peripheral power driver applications.

These smart power drivers UCQ5818AF and UCQ5818EPF have been designed with BiMOS II logic for improved data entry rates. With a 5 V supply, they will operate to at least 3.3 MHz. At 12 V, higher speeds are possible. Use of these devices with TTL may require the use of appropriate pull-up resistors to ensure an input logic high. UCQ5818AF and UCQ5818EPF can be operated over the ambient temperature range of -40°C to +85°C. The UCQ5818AF is supplied in a 40-pin plastic dual in-line package with 0.600" (15.24 mm) row spacing. A copper lead frame, reduced supply current requirement, and low output saturation voltage permits operation with minimum junction temperature rise. The 'A' package allows all 32 outputs to be operated at -25 mA continuously over the operating temperature range.

For high-density packaging applications, the UCQ5818EPF is furnished in a 44-lead plastic chip carrier (quad pack) for surface mounting on solder lands with 0.050" (1.27 mm) centers. The PLCC of UCQ5818AF and UCQ5818EPF allows -25 mA continuous operation of all outputs simultaneously at ambient temperatures to 60°C. Similar devices are available as the UCQ5810AF/LWF (10 bits), UCQ5811A (12 bits), and UCQ5812AF/EPF (20 bits).
