FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DLO31F-series device is a gated delay line oscillator. 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 phase during
oscillation, but return to opposite logic levels when the device is disabled.
