    摘要: A push-pull driver circuit wherein the input signal (1) is applied to turn on one (6) of two transistors (5, 6) mounted in series and the inversion of that signal is applied to the second transistor (5) in the series path and the output taken from between then operates to isolate the load and since one and only one of the two transistors in the series path is conducting there is a path to charge and discharge the load capacitance (3) but no path through both devices for power dissipation. The driver circuit can be built into a 2-bit partitioning circuit (23) which in turn, when used with a programmed logic array (20) and the relative capacitance of the various parts being isolated from each other byacoupling circuit (54) , the resulting assembly provides a high performance programmed array logic device.

    摘要: A PLD comprises a programmable first AND array whose inputs are selectively connectable to input lines and whose outputs are selectively connectable to a programmable second OR array. The PLD further comprises a programmable third AND array whose inputs are selectively connectable to the input lines, and whose outputs are fixedly connected to inputs of a fixed fourth OR array. The outputs from the second OR array are also connected in a fixed manner to the fourth OR array. This arrangement overcomes some of the weaknesses in both the conventional PAL and PLA architectures while retaining most of their strengths.

    摘要: An input transition detection circuit for detecting when an input signal switches states, the input transition detection circuit then providing a time delay signal at a time delay signal node to enable a zero-power part to wake up from a low power mode. The input transition detection circuit (400) includes two inverters (402, 404) and four transistors (406, 408, 410, 412) compared to the two inverters and nine transistors utilized in previous circuits. The two inverters (402, 404) are coupled in series for receiving and delaying the input signal. A first p-channel transistor (406) has its source coupled to receive the input signal and gate coupled to the output of the two inverters (402, 404). A second p-channel transistor (408) has its source coupled to the output of the two inverters (402, 404) and gate coupled to receive the input signal. A first n-channel transistor (410) is coupled to the drain of the first and second p-channel transistors (406, 408) and provides a current sink which draws less current than either the first or second p-channel transistors (406, 408) providing a voltage to control the gate of a second n-channel transistor (412). The second n-channel transistor (412) connects the time delay signal node to ground. The second n-channel transistor (412) enables the input transition detection circuit (400) to be faster than previous circuits since only one transistor (412) connects the time delay signal node to ground.
