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.
