DESCRIPTION
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 30. 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 500 pull-up resistor and a 500 pull-down resistor. (See Test Circuit). Reducing the load resistors to 100 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 = 30, RL = 100, RL = 300, and RL = 500.

NOTE: When using Open-Collector parts, the value of the pull-up resistor greatly affects the value of the tPLH. For example, changing the specified pull-up resistor value from 500 to 100 will improve the tPLH up to 50% with only a slight increase in the tPHL. However, if the value of the pull-up resistor is changed, the user must make certain that the total IOL current through the resistor and the total IILs of the receivers does not exceed the IOL maximum specification.
