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.
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°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.
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°C.
Similar devices are available as the UCQ5810AF/LWF (10 bits), UCQ5811A
(12 bits), and UCQ5812AF/EPF (20 bits).
