FEATURES

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 V

guarantees incident wave switching with V

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 t

propagation delay by approximately 50% while increasing t

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, R

and R

INPUT AND OUTPUT LOADING AND FAN-OUT TABLE

NOTE: One (1.0) FAST unit load is defined as: 20 A in the High state and 0.6mA in the Low state. OC = Open Collector.
