FEATURES
DESCRIPTION
The 74F30244 is a high current open collector octal buffer
• Ideal for driving transmission lines or backplanes. 160mA I ideal
OL
composed of eight inverters. The 74F30244 has non-inverting paths.
The device has eight inverters with two Output Enables (OE0, OE1),
each controlling four outputs. The driver is designed to deal with the
low-impedance transmission line effects found on printed circuit
for applications with impedance as low as 30Ω
• Guaranteed threshold voltages on the incident wave while driving
line as low as 30Ω
boards when fast edge rates are used. The 160mA I provides
ample power to achieve TTL switching voltages on the incident
wave.
OL
• High impedance NPN base inputs for reduced loading (20µA in
High and Low states)
• Ideal for applications which require high output drive and minimal
bus loading

LOAD RESISTOR (Ω)
NOTE:
When using Open-Collector parts, the value of the pull-up resistor greatly affects the value of the t
. For example, changing the
PLH
specified pull-up resistor value from 500Ω to 100Ω will improve the t
up to 50% with only a slight increase in the t
. However,
PLH
PHL
if the value of the pull-up resistor is changed, the user must make certain that the total I current through the resistor and the total
OL
I s of the receivers does not exceed the I maximum specification.
