The device produces a stable square wave which is synchronized with the falling edge of the Gate Input (GB). The frequency of oscillation is given by the device dash number (See Table). The two outputs (C1,C2) are in complementary during oscillation, but both return to logic low when the device is disabled.

Prospect Ave. Clifton, NJ 07013 1 DLO32F APPLICATION NOTES THERMAL STABILITY POWER SUPPLY BYPASSING The delay line used internally to develop the clock signals in the DLO32F has a thermal coefficient of 100ppm/C. For low frequency units, this is also the thermal coefficient of the output frequency. For higher frequency units, however, other internal effects must be considered, and the actual thermal coefficient may be somewhat higher. The DLO32F relies on a stable power supply to produce a repeatable frequency within the stated tolerances. A 0.1uf capacitor from VCC to GND, located as close as possible to the VCC pin, is recommended. A wide VCC trace and a clean ground plane should be used.
