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.
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.
Timing for the circuit is shown in Figure 1. Data input is
sampled on the positive clock edge. Data output changes
Each output sinks 250 mA and is internally clamped to
ground at 50V to dissipate energy stored in inductive loads.
