ABSTRACT:
An apparatus for generating digital gating signals respectively on an N-channel and a P-channel drive line in response to a digital data signal comprising a first and a second digital switching device, a resistive device, and first and second threshold devices for generating digital signals when receiving an input signal which exceeds a preestablished threshold value. The first and second digital switching devices commonly receive the data signal at their respective gates. The first digital switching device is operatively connected between a voltage source and the resistive device and generates a first gating signal from a juncture intermediate the first digital switching device and the resistive device. The second digital switching device is operatively connected between the resistive device and ground and generates a second gating signal from a juncture intermediate the resistive device and the second digital switching device. The first threshold device has a first preestablished threshold value, receives the first gating signal as its input signal, and generates a first digital signal representative of the first gating signal; the second threshold device has a second preestablished threshold value, receives the second gating signal as its input signal, and generates a second digital signal representative of the second gating signal. The first preestablished threshold value is preferably lower than the second preestablished threshold value.
