SCM410 logic levels are directly compatible with TTL and 5V CMOS logic families. Mixer logic may be used with
15V CMOS logic if a pull-up resistor is used with each GATE output. See Figure 14.
Note: For information on logic gate use, refer to the TTL Cookbook and CMOS Cookbook, both by D. Lancaster,
