PHILIPS 74F620/74F623 handbook

This document describes the features and characteristics of two octal bus transceivers, 74F620 and 74F623. They both have high-impedance NPN base inputs for reduced loading, making them ideal for applications that require high output drive and minimal bus loading. Additionally, they have 3-State buffer outputs with a sinking capability of 64mA and a sourcing capability of 15mA.
