G290 Writer Flip-Flop

Summary The G290 Writer Flip-Flop is a single-height circuit board module designed for use in the RS09 DECdisk system. Its primary function is to provide a -15V write voltage to the G285 Series Switch. The module consists of one JR flip-flop, two AND gates, and two power drivers. It features specific input pins for flip-flop control, direct clearing, and gate enabling, with output capabilities supporting both high-current drive (150 mA) for switching and low-current (10 mA) test outputs. The unit operates with a 90 ns input/output delay and has a total power dissipation of 1W.
