General Description

The MM74C240 and MM74C244 octal buffers and line drivers are monolithic complementary MOS (CMOS) integrated circuits with 3-STATE outputs. These outputs have been specially designed to drive highly capacitive loads such as bus-oriented systems. These devices have a fan out of 6 low power Schottky loads. A high logic level on the output disable control input G makes the outputs go into the high impedance state.

Features
