SG55327/SG75327
QUAD SOURCE MEMORY DRIVER
FEATURES
DESCRIPTION
• Quad source memory drivers
• 600mA output current capability
• VCC2 drive voltage variable to 24V
• Output capable of swinging between VCC2 and
ground
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.
• High-repetition-rate driver compatible with high–
speed magnetic memories
• Inputs compatible with TTL decoders
• Minimum time skew between strobe and output–
current rise
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.
• Pulse-transformer coupling eliminated
• Drive-line lengths reduced
HIGH RELIABILITY FEATURES - SG55327
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.
♦ Available to MIL-STD-883
♦ Scheduled for MIL-M-38510 QPL listing
♦ LMI level “S” processing available
These devices are available in 16-pin ceramic DIP, 16-pin plastic
DIP and 16-pin flatpack.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG55327 with -55°C ≤ TA ≤ 125°C, and SG75327
with 0°C ≤ TA ≤ 70°C. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.)
