Designed primarily for use with vacuum-fluorescent displays, the
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
CMOS serial data output enables cascade connections in applications requir-
ing additional drive lines.
The UCN5811A features 60 V and -40 mA output ratings, allowing it to
be used in many other peripheral power driver applications. It can be used as
an improved replacement tor the SN75512B. The Allegro devices do not
require special power-up sequencing.
The UCN5811A has 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 this device with TTL may require
the use of appropriate pull-up resistors to ensure a proper input logic high.
This device is supplied in a 20-pin plastic dual in-line package. It can be
operated over the ambient temperature range of -20°C to +85°C. Copper lead
frames and low output saturation voltages allow all outputs to be operated at
25 mA continuously at ambient temperatures of up to 76°C.
