2 / 8 page Philips Semiconductors Product specification 74F3038 Quad 2-input NAND 30 Ω line driver (open collector) 2 1998 May 21 853-0022 19433 FEATURES • 30Ω line driver • 160mA output drive capability • High speed • Facilitates incident wave switching • 3nh lead inductance each on V CC and GND when both side pins are used 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 Ω. 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 Ω pull-up resistor and a 500Ω pull-down resistor. (See Test Circuit). Reducing the load resistors to 100 Ω 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 = 30Ω, RL = 100Ω, RL = 300Ω, and RL = 500Ω.
