5818-F UCN5818EPF SERIAL DATA OUT LOAD SUPPLY LOGIC SUPPLY SERIAL DATA IN OUT30 OUT31 OUT32 OUT 1 OUT2 NC OUT3 BiMOS II 32-BIT SERIAL-INPUT, LATCHED SOURCE DRIVERS WITH ACTIVE-DMOS PULL-DOWNS Designed primarily for use with vacuum-fluorescent displays, the UCN5818AF and UCN5818EPF 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 allow direct interfacing with microprocessor LSI-based systems. A CMOS serial data output enables cascade connections in applications requiring additional drive lines. Both devices feature 60 V and -40 mA output ratings, allowing them to be used in many other peripheral power driver applications. These smart power drivers have been designed with BiMOS II logic for improved data entry rates. With a 5 V supply, it 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. All devices can be operated over the ambient temperature range of 20°C to +85°C. The UCN5818AF 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 c...
