tl/f/5817 DS3654 printer solenoid driver august 1992 DS3654 printer solenoid driver general description the DS3654 is a serial-to-parallel 10-bit shift register with a clock and data input, a data output from the tenth bit, and 10 open-collector clamped relay driver outputs suitable for driving printer solenoids. timing for the circuit is shown in figure 1 . data input is sampled on the positive clock edge. data output changes on the negative clock edge, and is always active. enable transfers data from the shift register to the open-collector outputs. internal circuitry inhibits output enable for power supply voltage less than 6v. each output sinks 250 ma and is internally clamped to ground at 50v to dissipate energy stored in inductive loads. connection diagram dual-in-line package tl/f/5817 1 top view order number DS3654n see ns package number n16e pin descriptions pin no. function 1 output enable 2 output 6 3 output 7 4 output 8 5 output 9 6 output 10 7 data output 8 ground 9 clock input 10 data input 11 output 1 12 output 2 13 output 3 14 output 4 15 output 5 16 v cc logic diagram tl/f/5817 2 c 1995 national semiconductor corporation rrd-b30m105/printed in u. s. a.
