The 74F3038 is a high current Open-Collector Line Driver composed of four 2-input NAND gates. It has been designed to deal with the transmission line effects of PC boards which appear when fast edge rates are used.
The 74F3038 can sink 160mA with a VCC as low as 4.5V. This guarantees incident wave switching with VOL not more than 0.8V while driving impedances as low as 30W. This is applicable with any combination of outputs using continuous duty.
The AC specifications for the 74F3038 were determined using the standard FAST load for open-collector parts of 50pF capacitance, a 500W pull-up resistor and a 500W pull-down resistor.
Reducing the load resistors to 100W will decrease the tPLH propagation delay by approximately 50% while increasing tPHL only slightly. The graph of typical propagation delay versus load resistor (see AC Characteristics section for Graph) shows a spline fit curve from four measured data points, RL = 30W, RL = 100W, RL = 300W, and RL = 500W.
