74F30244
Octal 30line driver with enable, inverting (open collector)
Octal 30line driver with enable, non-inverting (open collecor)
FEATURES
Ideal for driving transmission lines or backplanes. 160mA IOL ideal
for applications with impedance as low as 30
Guaranteed threshold voltages on the incident wave while driving
line as low as 30
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 VCC 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 (OE0, 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 IOL provides
ample power to achieve TTL switching voltages on the incident
wave.

a. 50% duty cycle,
AND
b. 3/5 of remaining 50% driving 100mA (leaving the remaining 2/5 of the drive 160mA)
OR
c. use 450 linear feet per minute forced air or other thermal mounting techniques.
