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.

FEATURES

• Ideal for driving transmission lines or backplanes. 160mA IOL 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 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
