UCN5811A smart power BiMOS II driver features low-output saturation

voltages and high output switching speed. These devices contain CMOS shift

registers, data latches, and control circuitry, and bipolar high-speed sourcing

outputs with DMOS active pull-down circuitry. The high-speed shift register

and data latches allow direct interface with microprocessor-based systems. A

12 V, higher speeds are possible. Use of this device with TTL may require

the use of appropriate pull-up resistors to ensure a proper input logic high.

frames and low output saturation voltages allow all outputs to be operated at

25 mA continuously at ambient temperatures of up to 76°C.
