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