INTEGRATED CIRCUITS 74F3038 Quad 2-input NAND 30 Ω line driver (open collector) Product specification Supersedes data of 1990 Jan 29 IC15 Data Handbook 1998 May 21 Philips Semiconductors Product specification Quad 2-input NAND 30Ω line driver (open collector) FEATURES 74F3038 PIN CONFIGURATION • 30Ω line driver • 160mA output drive capability • High speed • Facilitates incident wave switching • 3nh lead inductance each on VCC and GND when both side pins D0a 1 16 Q3 D0b 2 15 D3b Q0 3 14 D3a GND 4 13 VCC GND 5 12 VCC D2a are used DESCRIPTION Q1 6 11 D1a 7 10 D2b D1b 8 9 Q2 SF00570 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 30Ω. This is applicable with any combination of outputs using continuous duty. TYPE TYPICAL PROPAGATION DELAY TYPICAL SUPPLY CURRENT (TOTAL) 74F3038 6.0ns 17mA ORDERING INFORMATION The AC specifications for the 74F3038 were determined using the standard FAST load for open-collector parts of 50pF capacitance, a 500Ω pull-up resistor and a 500Ω pull-down resistor. (See Test Circuit). Reducing the load resistors to 100Ω 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.

For example, changing the specified pull-up resistor value from 500Ω to 100Ω 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.
