SG55327/SG75327 QUAD SOURCE MEMORY DRIVER DESCRIPTION FEATURES 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. * * * * Quad source memory drivers 600mA output current capability VCC2 drive voltage variable to 24V Output capable of swinging between VCC2 and ground High-repetition-rate driver compatible with high- speed magnetic memories Inputs compatible with TTL decoders Minimum time skew between strobe and output- current rise 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 -55C to 125C while the SG75327 is characterized from 0C to 70C. 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.
