Product specification
Octal 30 line driver with enable, non-inverting (open collector)
74F30244
FEATURES
* Ideal for driving transmission lines or backplanes. 160mA IOL ideal
for applications with impedance as low as 30
DESCRIPTION
The 74F30244 is a high current open collector octal buffer 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 boards when fast edge rates are used. The 160mA IOL provides ample power to achieve TTL switching voltages on the incident wave. TYPICAL PROPAGATION DELAY 10.5ns TYPICAL SUPPLY CURRENT (TOTAL) 69mA
* Guaranteed threshold voltages on the incident wave while driving
line as low as 30
* High impedance NPN base inputs for reduced loading (20A in
High and Low states)
* Ideal for applications which require high output drive and minimal
bus loading
* Octal interface * 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)
TYPE 74F30244
* Available in 24-pin standard slim DIP (300mil) plastic or SOL
ORDERING INFORMATION
DESCRIPTION 24-pin Plastic Slim DIP (300mil) 24-pin Plastic SOL1 COMMERCIAL RANGE VCC = 5V 10%, Tamb = 0C to +70C N74F30244N N74F30244D PACKAGE DRAWING NUMBER SOT222-1 SOT137-1
NOTE: 1. Because of the high current sinking capability of these parts, the SOL package should only be used under the following conditions: 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.

NOTE: When using Open-Collector parts, the value of the pull-up resistor greatly affects the value of the tPLH. For example, changing the specified pull-up resistor value from 500 to 100 will improve the tPLH up to 50% with only a slight increase in the tPHL. However, if the value of the pull-up resistor is changed, the user must make certain that the total IOL current through the resistor and the total IILs of the receivers does not exceed the IOL maximum specification.
