Hi,
See page 6 of this PDF (Fig.3).

(fig 3). If you set Control A to "1" the current will flow
in one direction in the motor winding (or your solenoid) and if you
set Control A to "0" the current will flow in the opposite direction
in the motor winding (or your solenoid).
Same for Control B (Your second solenoid).
External diodes are mandatory!

With two IC 7406 (inverting buffer), three IC SN754410 and 24 diodes you
can drive your six solenoids.
(You can find similar driver ICs with built-in diodes).

Edit:
One IC with built-in output clamp diodes for inductive transient suppression is the L293D.
The "D" at the end is for Diodes. The model L293 is without diodes.
See page 8 of this PDF.
