FEA TURES
•Ideal for driving transmission lines or backplanes. 160mA I
OL
ideal
for applications with impedance as low as 30Ω
•Guaranteed threshold voltages on the incident wave while driving
line as low as 30Ω
•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
•Octal interface
•74F30240 inverting
•74F30244 non-inverting
•Open-Collector outputs sink 160mA
•Multiple side pins are used for V
CC
and GND to reduce lead
inductance (improves speed and noise immunity)
•Available in 24-pin standard slim DIP (300mil) plastic, SOL or
CERDIP packages
DESCRIPTION
The 74F30240 and 74F30244 are high current open collector octal
buffers composed of eight inverters. The 74F30240 has inverting
data paths and the 74F30244 has non-inverting paths. Each device
has eight inverters with two Output Enables (OE
0, OE1), each
controlling four outputs. Both drivers are designed to deal with the
low-impedance transmission line effects found on printed circuit
boards when fast edge rates are used. The 160mA I
OL
provides
ample power to achieve TTL switching voltages on the incident
wave.

TYPICAL PROPAGATION DELAYS VERSUS LOAD FOR OPEN COLLECTOR OUTPUTS
NOTE:
When using Open-Collector parts, the value of the pull-up resistor greatly affects the value of the t
PLH
. For example, changing the
specified pull-up resistor value from 500Ω to 100Ω will improve the t
PLH
up to 50% with only a slight increase in the t
PHL
. However,
if the value of the pull-up resistor is changed, the user must make certain that the total I
