Octal Buffers and Line Drivers with TRI-STATE

Outputs
General Description
These octal buffers and line drivers are monolithic comple-
mentary MOS (CMOS) integrated circuits with TRI-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. For
improved TTL input compatibility see MM74C941.
