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. 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 VCC and GND to reduce lead TYPE TYPICAL PROPAGATION DELAY TYPICAL SUPPLY CURRENT (TOTAL) 74F30240 9.5ns 62.5mA 74F30244 10.5ns 69mA inductance (improves speed and noise immunity) • Available in 24-pin standard slim DIP (300mil) plastic, SOL or CERDIP packages ORDERING INFORMATION DESCRIPTION COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0°C to +70°C PACKAGE DRAWING NUMBER 24-pin Plastic Slim DIP (300mil) N74F30244N SOT222-1 N74F30244D SOT137-1 24–pin Plastic SOL1 NOTE: 1.

For example, changing the specified pull-up resistor value from 500Ω to 100Ω 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.
