C OPERATION
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 high-
speed sourcing outputs and DMOS active pull-down circuitry. The high-
speed shift register and data latches allow direct interfacing with microproces-
sor LSI-based systems. A CMOS serial data output enables cascade connec-
tions 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, 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. All devices can be operated over the ambient temperature range of
-40擄C to +85擄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 鈥楢鈥?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 allows -25 mA continuous
operation of all outputs simultaneously at ambient temperatures to 60擄C.
Similar devices are available as the UCQ5810AF/LWF (10 bits), UCQ5811A
(12 bits), and UCQ5812AF/EPF (20 bits).
