ABSTRACT:
An output driver circuit an integrated circuit memory device prevents crowbar currents from occurring. The output driver uses just one resistive element having multiple taps so that the amount of silicon area used for slew rate control is minimized. The signals which control the output driver devices are carefully balanced for no skew and cross at a voltage level of Vcc/2 so that there is no crowbar current generated during tri-stating of the output driver output signal.
