This article describes a general-purpose logic circuit for gate arrays in which p-type FETs (field-effect transistors) are used as active pull-ups to perform a NOR function, with a resulting high performance and low power consumption. The DTL (diode-transistor logic) NOR function is similar to two, one-way DTL NAND circuits with dotted collectors, which produce a two-way NOR. A power saving is achieved with this circuit by the use of a complementary FET-bipolar NOR combined with a unique base drive resistor configuration.
