DESCRIPTION
The SG55327/SG75327 is a monolithic quad source driver
designed to meet the high current and fast switching speed
requirements of magnetic memory systems. Each driver is
independently controlled and capable of sinking up to 600mA.
Paired with the SG55326 Quad Sink Driver, the SG55327/
SG75327 provides the current drive necessary for many sink/
source applications.
The SG55327/SG75327 has also been used in many non-memory
applications:
for example, as the driver for a clock circuit, relay,
lamp, or small motor, or any application where a 600mA source
driver is needed.
The SG55327 is characterized for use over the full military
operating ambient temperature range of -55
°
C to 125
°
C while the
SG75327 is characterized from 0
°
C to 70
°
C.
These devices are available in 16-pin ceramic DIP, 16-pin plastic
DIP and 16-pin flatpack.
