IMPROVED TRISTATE CONTROL CIRCUITRY FOR A DRIVER CIRCUIT
摘要
Improved tristate control circuitry is provided for a driver circuit formed on an integrated circuit chip. A parallel-connected combination of a depletion mode transistor and an enhancement mode transistor is connected in series in the voltage supply path for the driver circuit for controlling whether the driver circuit is in an active mode or a standby mode by controlling the supplying of operating voltage thereto. A further enhancement mode transistor provides a shunting action between the driver circuit side of the parallel-connected transistors and circuit ground to further aid in the control of the driver circuit operating mode.
